So If I sit here and tell you to "imagine" or picture an apple in your head, you can vividly see the apple and "imagine" it. But where exactly are you "seeing" that image at? Like right now I can picture any complex image at will, and I can see it, but where am I seeing this image at? I get its "in my head" but that doesn't explain the visual image i am creating, in some other dimension or something. It's like day dreaming you're creating really complex scenes and moving images but where and how are you picturing those?

what would happen if you observed something before the quantum wave form collapsed? Like could you open up a closet door quick enough?
