How to get an astral projection

Title explains it XD

you mean astral projection from a LD?

I would suggest working on relaxation techniques while awake if you're trying to project from your dreams; I'm no expert, but I know that when I was working on relaxation and meditation, I had way more out of body/AP experiences while asleep. In fact, that's when my first experiences like that occurred! I would also suggest buying a book or two on the subject.

For some people, AP takes no practice, but those people are few and far between. You have to be very patient with yourself and the process.

I think that in order to astral project you need even GREATER awareness than what you normally have in a lucid dream. When you lucid dream try flying UP and increase your awareness more and more as you go up until you SHIFT into the astral world. I never tried this. Just giving my 2 cents
