Ive had similar experiences. Especially one in kindergarten, at age 5, our teacher did a guided meditation tape during nap time and i left my damn body 100%.
I later had experiences with dreams of my own life in the future but an alternate timeline future... its actually how and where i came up with the idea for the MEQUAVIS and NanoCheeZe.... believe it or not. I used it in a dream of my own alternate future.... lol and i was lucid enough to have asked questions and took notes upon waking ;) there is a reason remote viewing is used by spying groups and is mostly classified. Whatever the astral plane really is, is very very real. I tend to think of it as more of a Quantum Nexus however. Who knows tho. Imaginations can also be one hell of a thing haha!
Thank you so much for sharing!
It seems that the earlier in life a person learns the technique of setting aside the material conscious mind, to allow the subconscious and superconscious soul minds to explore the fourth dimensional astral plane, lucidity becomes easier to recognize as we mature and explore with greater intention.
By the tremendous nature of your creation, it is clear that you asked the correct questions. Had your ideals not been as noble, it is possible the answers coming back might not have been so forthcoming!
Alternate timeline future seems like the Prophesy which served its true purpose in affecting the change necessary to change that otherwise predictable outcome.
Have you already published a detailed account of these experiences? If not, then I would strongly encourage you to do so!
