Could someone explain to me the difference between AP and just dreaming?? I've also heard you can meet other people who are Projecting themselves?

Could anyone tell me how to do this? My boyfriend talks about it a lot, and has claimed to have done it before. I'd like to know how so I can join him. It'd be interesting to see if it works.

Haah, I do sound a bit insane, don't I?

Also if you know any good informative websites that'd be great too

Thanks!
