Astral Projection is actually very real, indeed. As mentioned above, it takes some effort to manage to do it, but eventually you'll get there. Something that really helped me with astral projection was meditation . Moreover, I used to make a major mistake most people make when they attempt to astral project. I tried, and I tried *too* hard. I really wanted to project but I just couldn't let go. I wouldn't let go. Not out of fear, not out of doubt, but only because I was trying too hard. So I took it slow. I focused on meditation, relaxation and basically I made meditation a daily practice. You need to be able to relax yourself fully and then let go.
That is what I did basically. I would light some incense to relax myself fully, I'd light some candles , play some relaxing music (binaural beats may be extremely helpful). Also, in my experience, lots of people, if not most people, are afraid of it. They're afraid of letting go. They're afraid of the "unknown" which is why they can't do it. If that is the case, you can use protection. Protective amulets, talismans, protective herbs, or even crystals would be a great idea. Lots of people cast a circle before they attempt to astral project. These tips can be really helpful and can help you eventually get there. Try them. Once you do it, you'll know it's real. You'll know you've done it. No doubts. Hope this helps.
