Not sure where to put this, so I figure a general area is good.
I borrowed a book called “Get High Now (without drugs)” by James Nestor. It is full of all sorts of bizarre and interesting things - weird visual things that show how our eyes function/malfunction, weird sound related things and stuff that can alter the way our brains function (briefly), including different types of meditation.
It isn’t specific to lucid dreaming, but there is so much in here to try and play with that it is well worth checking out.
