Abstract

I praise Metzinger's book _On Being No One_ by calling my essay "Finally Some One" meaning that I am pleased to see a first rate philosopher so carefully reading the neurobiological literature. Especially as it pertains to sleep and dreaming. Metzinger is comprehensive and comprehending. By studying the neurobiological substrates of normal dreaming, lucid dreaming and related altered states of consciousness (such as out of body experiences, hypnosis, and deja' vu), we may gain insight into the general rules governing brain activity in relation to subjective experience
