Hi, last night I was the closest to astral projection ever in my life. About 20 minutes in, I was really relax, and was about to slip into sleep, suddenly I felt a vibration in my legs which made me wake up and focus instantly, this occurred twice. But the problem is that the vibration is only there for like 1 second. I read a lot from this website is to not be excited or the vibration will go away but I didn't even have time to be excited, the vibration just spring up like a flash and then go away. How can I keep the vibration?? or at least induce it?
I doubt those were the vibrations your looking for, as vibes are more gradual in how they tend to come up and disappear. It's not really a quick one-second thing.
Just do whatever you do for an AP attempt, and vibes will normally come on their own during the process. If they don't, don't assume your not making progress. They can be a signpost, but not necessarily to judge your progress.
