I am speaking specifically of two “dangers” mentioned by a friend of mine. He had experienced lucid dreams in the past.
1.) He stated that lucid dreaming would result in the same affects as if the body had not gotten any sleep due to a lack of REM sleep. Is this true with ANY form of lucid dreaming?
2. ) He also mentioned deja vu experiences, though from what I’ve seen, it appears this can be avoided by simple reality testing.
