Astral Travelling and Lucid Dreaming
It’s interesting to note how little of what is around us we are actually aware of. As a quick example, dogs can hear high pitched sounds far out of our hearing range, and cats have far better night vision than us. There are obviously many, many other examples, where the human being just doesn’t get near to the environment around: there are so many different colours of light which are well beyond us. Then think about radio waves and telephone signals that are all around 24/7.
Outer body experience is something that is recorded on numerous occasions, and would seem to be likely to be real events rather than something imagined or faked. Nonetheless, the gathering of serious scientific evidence continues to be problematic, for obvious reasons.
