Sometimes I will be imagining a conversation with someone, not a made-up person or "imaginary friend" or anything, but a person I know that i am just imagining, like a daydream, and then I realize that I am actually talking to the person. Like I will imagine them saying something, then I laugh and actually talk back to them out loud. I am glad no one has walked into my room before while I was doing this, they might be kind of concerned. Is this normal? Is there anybody else who finds themselves doing this?
