The Sun and the Shadow: My Experiment With Lucid Dreaming

I found it useful as some information in it helped me to have a really elaborate lucid dream. There is a religious perspective and some religious dreams, I don't believe in God, but I did not find any problems with that in this context, it was interesting. It is for the general reader and it has some simplified Carl Gustav Jung concepts thrown in. It is quite old, but it mostly just describes the dreams the writer and some other people had, things people dream about don't have an expiration date unlike science I guess.
