I had that happen in my childhood as well. I'm unsure why that is. But, I do remember it freaking me out then. I distinctly recall getting up at night once (around age 5) and seeing the hallway to the bathroom dramatically stretching out (like in that movie, Poltergiest).

I also have memories of fully detaching from myself around that same time (5-ish) and watching myself from way above. What I saw myself doing below is a blur to me. Those two memories have always bothered me & here I am....almost 40 years later and feeling the same way I was then! I haven't ever discussed these things with anyone, because I felt weird and uncomfortable.

Anyway, I understand what you described very well. (((hugs)))
