A MIND IS A TERRIBLE THING TO WASTE
Read the minds of everyone ever

To gain this achievement you'll have to read every mind in 7 different chapters. This isn't as bad as it sounds though because the maps of each level will actually show you via a little dot where each mind is. Also when flipping through chapter select there'll be a counter for each level that shows how many total there are and how many you actually have making clean up a little easier for you.
You have to read minds in chapters 3,4,5,6,7,9 & 10


DROWNED SKELETONS
Read the minds of the drowned skeletons

This is located to the far right of this level. You gain access to it as soon as you give the dog the teeth from the crocodile and make the two guys in the black suits run away. As soon as the dog scares the guards off move to the end of the pier and you'll see two of them sitting under the water you only actually need to read the mind of one of them to gain this achievement.

If your doing this to progress through the story make sure you do it before freeing the guy from the trunk because that'll end the chapter.

DECOYCEPTION
Have enemies chasing other enemies chasing you

To get this achievement you must read the mind of one of the enemies on the 2nd floor up from the bottom when looking at the map. You'll know it's the right enemy because as you read his mind he'll ask something along the lines of "let me know if you seen this man" after his short thought a sticker of your characters face will appear in his thought bubble for you to grab.

Now with the sticker in hand you can attempt this. There are actually 2 enemies in this little area where you got the sticker and you'll want to stick it on the one close to you. To do this jump down off the little nook your standing in and get the first one's attention, as soon as you have his attention slap the sticker on him. If done right the one further down should now chase the one with the sticker on him and as long as you run a short distance with the decoy chasing you and the other enemy chasing the decoy this achievement will pop.

LADY IN THE SKY WITH DUCKY
Return a totally sweet alien to the stars

To get this achievement you'll have to help the lady on the roof get back to space. To help her do this you must go retrieve her duck floaty thing that's located on the lowest level to the far left. Once you have it make your way back up to her and give her the duck.


TOWER OFFENSE
Climb the asylum tower without alerting any nurses

For this achievement you must ascend the tower in this level. The tower is pretty obvious when you look at the map it's the piece of the level dead smack in the center that goes higher then the rest of the level. There are 2 spot lights you must avoid and 3 nurses to get past. I'll list the steps on how I did this and what I feel is the easiest way of doing it. It's also important to note you don't have to restart the entire level for this just get caught by a nurse and it'll spawn you back at the bottom of the tower.

• Make your way to the second nurse doesn't matter if they see you at this point all you trying to get is the sleepy sticker from her
  
• Once you have it let yourself get caught to reset it (you'll still have the sticker)
  
• To the right of the first nurse you'll see a thumbtack you can grab a hold of that'll let you completely by pass the first nurse grab it.
  
• Now make your way as close to the second nurse as possible and hit her with the sticker putting her to sleep for a moment.
  
• During this moment make your way up the right side again. Don't go to far onto the next ledge or the third nurse will spot you, instead wait on the edge for the second nurse to wake back up and you'll repeat the first step to get another sleep sticker.
  
• Once you have this sticker hurry up and hit the third nurse with it and your home free just make your way to the top

Once you've made it to the top wait a second and the achievement will pop. If it doesn't you were probably spotted and just need to try again.


SUBCONSCIOUS EXPERIENCE
Read Harry's mind while he's passed out

You'll run across Harry just by progressing through this level. He's the guard who appears when you give the guy digging the tunnel the good news. To scare him all you have to do is complete the tea set, then take said tea set over by the tunnels and place it on the table by the rabbit and the ghost girl this will start a cutscene and the end result is a unconscious Harry. Now just read his mind and this achievement is all yours.


CAREFUL WHAT YOU WISH FOR
Read the mind of a lonely cat

You'll find the dead cat over in the upper right side of the map being held by a crazy lady petting and praising the cat. You can't do anything just yet other then read their minds which is helpful for the achievement for reading every persons mind. So to get this you have to go up to the roof, you can find your way up to the roof by grabbing a hold of the thumb tacks and stuff on the left side of the map until you reach the roof.

Once on the roof you'll run into a guy who says he's cheese. Read his mind and fast forward through his jingle and he'll form a thought bubble with a dead mouse sticker. Take this sticker and make your way back to the cat. Once there the lady will drop the cat and try to get the mouse from you. Now all you have to do is read the mind of the now lonely dead cat on the ground.


CREW OF THE DEAD

Once you've made your way to the ambulance just peel off the paper and it'll reveal 3 skeletons you only have to read the minds of the 2 standing for this trophy but might as well read all 3 of them while your there for the A Mind is a Terrible Thing to Waste achievement.

EUREKA!
Give poor Ron the perfect idea for a date

You can find Ron in the top of the police station behind a piece of paper you have to peel away. He needs your help and help him we will. Do a quick mind read on him before progressing much further to get his empty sticker bubble to appear. Now progress through the chapter until you reach the scene with the helicopter pilot talking to his girlfriend. Before you leave this area peel back the paper just behind the pilots girlfriend and you'll find a poster. Once you have the poster run back to the police station and deposit it in Ron's item bubble and this achievement is all yours.


FOOD FOR THOUGHT
Read the mind of an eaten fish

You'll first see the bird early in the level, on the billboard that says "Electrifying! Donna Grandiosa", but he won't have the fish just yet. So for now just continue past him. After you've completed the second helicopter section and the cutscene has played out you'll want to make your way back to the bird. This time when you check to read his mind there'll be another brain in the birds stomach that belongs to the fish. Just read it and this achievement will pop.


THE BIRD IN THE SKY
Never get noticed by the helicopter

For this you must get through 2 small sections without getting spotted by the helicopters that go back and forth. This cannot be reset like the the one for getting through the tower. You must do it with a flawlessly so this means restarting the level to try again.

Section 1
This is quite easy actually. First move as close to the edge of the over hang as you safely can and wait. To your far right there'll be a thumb tack you can grab a hold of. You want to grab this as soon as the helicopter passes it when it's strafing to the right and if done correctly you'll have just enough time to jump up the platforms and run down into the little nook that'll act as a safe zone. From here all you have to do is wait for the helicopter to pass you on its strafe to the left when it passes just run for it and you'll easily make it out of this first little section.

Section 2
For starters you need to read the mind of the first guard and he'll give you a sleepy sticker. Chances are though he moved before you can get it so just sit still and hug the back wall or he'll spot you. When he shows up above you again take the sticker and hit him with it.
From here run to the left as soon as the coast is clear and you'll find your first safe zone. Be quick though before the previous guard wakes back up. You'll have to jump towards the top as soon as the helicopter goes to the right. When this happens jump up and grab the tack just to your left and run for it. You'll know you'r safe when the cutscene of the pilot talking to his girlfriend starts.

Some usefull information from MIRAGE

FYI for 'Bird in the Sky', you do not have to restart the level if you screw up. Make sure to hit a save point before starting each helicopter section. If you are spotted, immediately quit the game to the main menu, and then continue your game. You'll be back at the save point without the game remembering you were spotted. I did this about a dozen times for the second section and got the achievement no problem.

OUT OF HIS MIND
Read Ray's mind

As soon as chapter 9 starts the unknown enemy will have Ray hooked up to a machine to suck the alien mind reading jelly brain from him. As soon as the brain becomes lodged in the tubed go into the mind reading mode and just read Rays mind.


UNNATURAL TALENT
Read Luigi's mind while he's singing

This will become available through normal story progression. Take the guitare from one Elvis to the other one and take his lips once you did so. Put the Elvis lips sticker on the zombie dressed in black who's stands on the podium. Now read his mind and voila.


DANGEROUS WORK
Mind-read the recently departed

This will become available just by progressing through the level. As soon as you give the present to the zombie talking to the blond nurse the zombie will drop the present and trigger the shotgun that ricochets a few times before eventually hitting the blond nurse in the chest and kill her. Now with the nurse dead all you have to do is read her mind.


LOVE IS BLIND
Read the minds of an unexpected couple

This will become available as soon as you give the yeti the hair to progress through the door the guard is blocking. After giving the yeti the hair she'll run out of her cell and grab the guard and run through the door. Follow them out and you'll see them sitting together. Just read each of their minds and you get this achievement.


CONGA LINE!
Get chased by 5 enemies at the same time

After you make the missile blow up the door while you progress in the story you'll enter in this mess of ledges and platforms to hop around on. This is where you need to be. There are exactly 5 guards located in this small area and the only real advice I can give you is try and get spotted by the light and it'll sound an alarm that attracts the guards . Once they are all chasing you and you make it out alive you will get this achievement.
