I had the same experience as this guy but no one beleived me. My sitter was amazed that I was talking to these 'people'. Most people just drool and laugh. I went months thinking I was the only one until my friend showed me this guy on youtube. My theory is the process of getting out of this reality is what most people experience, but once your all the way out, you are able to communicate with them. Watching him freak out and not wanting to be in this reality makes me wonder why I was so willing to come back in.
