I remembered having read something about one of the symptoms you described, because my wife once told me that she suffered the same as a child.
I am talking about the sensation as if everything is really far away, or small.
For now, my memory has left me in the dark, so I started Googling and found this little piece of text:
" Metamorphopsia is the distortion of visual images in their size, shape, and color. This has been termed the "Alice in Wonderland Syndrome," and is named after the events described in Lewis Carroll's book Through the Looking Glass "
It turns out that the writer of Alice in Wonderland suffered the same condition, and was inspired to write the book because of that very sensation ( remember the cake's, mushrooms and drinks that made Alice grow and shrink ? ).
So, even tho it is less commonly known, it is a "normal" or harmless condition according to this layman

But please consult your doctor about this as well.
