Meeting People In The Astral Plane Options

Have any of you ever met anyone in the astral realm and exchanged information to confirm that they exist in real life?

Have heard of groups who help people astral travel, visit them while they sleep and pull them out of themselves and such. They have a website although I can't remember what it was called. Intresting all the same, I suppose the depth in which one sleeps would alter the effect... that of being able to pull someone out and be on reasonable enough "talking" levels... a better way to do it would be to spend some time syncronising with the group energy wise perhaps using one of those brainwave guided visual tapes each night before someone comes round and takes you out of yourself. It can be done.
