I have been having lucid dreams since i was a kid, i can remember dreams from when i was 5. I used to bleed from the nose lots as a kid in sleep, Waking/coming round with my father saying 'keep you're head back, keep you're head back', and i would wake to see my family standing around looking at me weirdly.
In life as an adult the dreams did not go away, i just got better control of how to see/know that i was dreaming. Then it became fun, Lucid Dreaming begun.
Proper.
I been seeing Angels in my sleep for a few years now about 4-6-ish, my priest knows and my T; so i'm treated as a puzzle.
I have to sit with my T and say how i see the anatomy of dreaming, that i see it as an outside influence of T.V or music or books or films. So 'i' know where it comes from, but there are things that are too powerful too just come from a memory.
I know i've never been to the center of the galaxy (not yet the 'universe, yet), but i did when i was like 9-10 in a dream. SO powerful i 'still remember it now, at 40. I was obsessed with sci-fi so i just explain that away easy, a healthy diet of a mind curious of the world it lived in.
Angels though, different thing all together; it leaves a feeling of warmth, and something else i have not got yet. very weird stuff, even for me..
