I don’t know if there is a connection but I had a spontaneous OOBE half a hour after my Meditation Mastery. I have heard of others Meditation Mastery users developing OOBE skill as a result of the work with that product.
The exit out of the body was particularly interesting, it was exactly when we fall alsleep but here only my body went to sleep my mind remained awake, when the physical body was completely asleep, I could feel my energy becoming smaller or contracting itself to the point I could feel an impression of separation between the body and the energy.
I was out I was floating I was seeing roofs of building those weren’t Spanish architectural style; the use of red bricks is typical of the North of France and Central Europe more generally, my guess is that I was somewhere in my hometown Brussels (Belgium), today, I go to Barcelona to spend the week end so I focused on being there I found strange that instead I was in someplace else, may be, I have to learn to navigate in that new environment I guess .
I also intended to contact some kind of guide or someone from that environment something showed up however it is impossible to describe , it was like something in my visual field fluctuate and expressed something, I also heard voice actually it was my own voice like in talking out loud, I was saying complete banality such as “the coffee is warm”
I will see if I have more OOBE in the coming days.
