That's interesting. I dabbled with some lucid dreaming when I was young. I was able to do it most of the times but at very basic level and without proper discipline or using most of the techniques they mentioned, but then stopped it for some reason. Might be interesting to give it another try.

I recall once picking up a random book about telepathy, again when I was pretty young, don't recall anything from the book, except it had many exercises mentioned, that will let you experience astral projection and things thing like. On the very last page, it had a warning that not to do these exercises without any professional as they can be dangerous physically and mentally. I found it really hilarious, that the warnings were on the last page and not the first page, if I had been doing them as I was reading, I wouldn't have seen them until I had reached the very end 😀

Would love to hear how your AP journey goes, and if the book helps with anything.
