Definitely a form of dissociation. Some people feel themselves drifting away, others just wake up in a new situation. I get both unfortunately. Depending on who is out at that time & why they came out, etc. I'm DID though. But as others said, dissociation is common, normal. When it interferes w/ your life, that's when it's a disorder. I've drifted only to reawake at the close of something or when my husband walks into the room. It's a deep defense mechanism we have here inside. Nobody can see that they come out. So one's on constant alert to notify us in a sense when "real" people are present.
Hope that helps some. Welcome to the group too!
