I am not sure about astral projection. I am leaning towards fake but I am not sure. I am not really sure how you can tell if something is astral projection or a Lucid dream. In lucid dreams just about anything can happen, so almost anything which makes up astral projection and be in a normal dream.

The only thing which would prove your doing astral projection instead of dreaming are things like remote viewing and shared dreams, which people normally have a hard time proving.
