Captivating meditations on sleep and esp. dreams. I may have mentioned this before, but Mother was fixated on her dreams, many mornings recalling them in detail. I have a very peculiar book of hers that purported to explain everything in dreams as some sort of signifier or signal or warning. Offers no research justifications beyond the way obvious: yes, dreaming dead people you knew have come back to life is scary and probably a warning that something unexpected is going to happen.
