I often feel 'merged with' another thing, phenomena...like firelight, running water, mechanical objects, etc......I really don't know where the distinction is - is it me or other? Unknown. I think is like what OP mentions. I think I feel deeply part of certain others things that are actually not physically my body.
I often used to daydream (?), and I still do, about one part feeling HUGE and riding a giant crayon! I realize this sounds weird, in print, but it's true. Sometimes I feel invisible - really, but this cannot be. When I'm in a public place, like shopping or whatever, I feel as if I am the ONLY one in that place and do not even process another being.
I've read this, in so many forms, on WP, and about autistim so often that I don't think it's some 'bad' personaltiy disorder, but part of autism in some way unknown.
Knaidle - interesting; I've thought/felt this, and even drawn it! As if we're a conduit to another in some way undefined.
