We are now nearing the end of the game and I know there are things in levels that we didn't get the first time through, especially in Black Velvetopia and the first few levels. What I am going to do now is go back through every level and pick up some of the things that we missed. If you don't care to do this that's no problem, you can just skip past this "Second Visit" part of this walkthrough. But if you'd like to collect the rest of the items (besides figments, because as I explained I'm not going through all those) then let's jump back into these worlds.
The second trip is to pick up any of the items we may have missed the first time through the levels, some of the first levels we didn't have all the required abilities and a few of the later ones I may have just missed some stuff so let's jump back into these minds and grab whatever we may have missed.
Since you're already right next to Edward we might as well jump back in there first, get out the door again and press 'Y' next to Edward.
NOTE: THIS PART OF THE WALKTHROUGH IS NOT 100% COMPLETE, BUT AS OF THE WRITING I DO NOT HAVE TIME TO FINISH IT AND IT IS NOT CRITICAL SO I FINISHED THE GAME INSTEAD OF EXTRAS, I APOLOGIZE, BUT THERE ARE OTHER PLACES TO FIND THIS INFO IF YOU REALLY NEED IT
We'll first go to Black Velvetopia because we're already right there, then for the rest of them I'm going to revisit in the order that we had first gone to them. Each time we are going to return to the Collective Unconscious since all the doors are here, it would just be silly to go find all the people again to stick doors on their heads...not to mention we don't know where Milla and Sasha have gone.
So, we're going to do all levels in order and to get back here if there is a Teleport dude in the level you can do what we just did and have them bring you back right here or you can use your Smelling Salts (in your Backpack), which will take you back to the last spot you were in the "real world", or you can talk to Cruller (with the Bacon) and tell him you want to go to HQ and then get in the UTS and travel to Nein's Lab then re-enter the Brain Tumbler which will bring you here, to the Collective Unconscious.
