Yes, a lot...I often find it very hard to remain 'present'. It's easier to be in my head.
Yes, me too. I sometimes get annoyed when people try to drag me out of my head and engage me in a conversation, because I'm more comfortable there. I think this phenomenon actually gets to the essence of autism - the word autism means "self-ism", that is, the person is absorbed in their own mind/world and therefore less engaged with the world around them. Severely autistic youngsters are in that little world of their own all of the time, and a lot of effort from parents and carers goes into getting them to come out of it as much as possible.
My school reports when I was a child all complained about my constant "daydreaming" and I do it as much now as I ever did. If I begin to find things going on around me overwhelming, like being with someone who talks too much, I automatically retreat back inside my head and am no longer aware of what is going on around me, though I have learned to switch on a kind of autopilot which allows me to make interested noises duing pauses in the conversation, to fool the other person into thinking I am listening.
