Are astral projections real? or are they simply some vivid lucid dreams.

I mean, the whole process for astral projecting sounds like a WILD for me. Can someone write here the main difference between astral projection/doing the Wild? It really confuses me, because I find that the process to astral projection is almost identhical as doing the wild technic except for a few things.

I would be really gratefull if someone could explain this to me. Because as I see it, astral projection is nothing else than a common induced lucid dream. Thx!
