Well ok, I'm 44 years old this year and I'm finally at the point in my APing where I can AP whenever I want. That's to say, if I feel like going out I can always get out of my body without problems. This has been about a 25 year journey for me because I started reading about astral projection when I was around 18. It's so cool to be at this point and be able to explore and experiment.
My best advice on how to do it is to watch yourself falling asleep. The more you do it the more easy it gets. You'll begin to feel heavy and then misty as the lights slowly dim in your brain. The trick is to keep watching yourself fall asleep. Otherwise, there comes a point where lucidity will just stop and you veer off into the void.
So while you're watching yourself fall asleep stay aware of the threshold for exiting. At some point you'll know you are enough asleep to exit. It's good to be patient and relax instead of forcing it. Forcing it can sometimes be painful and you'll just end up with a headache.
I do all kinds of things when I AP. Just today I took a nap and had an AP. My bed is right next to a wall so I usually roll out of my body and exit through the wall instead of my front door. It's easier that way. Once outside I floated above the neighborhood and could see all the houses from about 100 feet in the air. My guide took over then and I started flying down the street faster and faster. It was dusky yet I could see every house and trees in prestine detail. Sometimes I like to do everything myself and choose exactly which direction to go... but sometimes I let the guiding force take me away.
I eventually made it to the city proper and like most of my APs it was a completely new location. Usually my APs start at my house where everything is familiar and things gradually change into new vistas that are completely different. I saw a beautiful grand church approaching as I gently raced toward it. It had arches and towers and steeples and was completely detailed. That's where the guiding force gently put me down right in front of the big wooden doors. I opened the door and went inside.
The first thing I noticed was the smell. I could smell incense and candles burning. It's rare for me to see open flame but sure enough the anteroom was full of purple candles and smoke from incense holders. When I looked into the church I could see lots of benches and the inconography was intense. Above were pictures of Jesus and Bhuddha and some Indian gods too I think. They where so detailed and beautiful I thought that this place had to be more than a dream. There's no way my imagination was this good.
I woke up a little after that with that incense smell still lingering in my nostrils. That's was just today though. I won't post all my APs here, just the good ones and the most exciting. Sometimes I learn a big lesson from an AP... I'll try to share those too.
Thanks for reading and please also share with me your techniques, APs, any advice or whatever...
