That dumbass "Ellimist" or whatever doesn't know nothing of nothing ! Firts, YES it is possible to enter in someone else's dreams because i've tried and did it. The point is, you cannot say that it isn't real when there are people out there *like myself* that succeeded. There is a book that you should look up to, is called "Practical Guide to Astral Projection" by Melita Denning and Osborne Philips. It's pretty good and it will teach you everything that you want to and NEED to. Good luck^^
