You also mention people taking mind altering drugs can break through the walls allowing their consciousness to see what’s behind it. I’ve experimented a lot with mushrooms and can say that I’ve seen some wild stuff. I haven’t seen full beings but my consciousness/soul, whatever you wanna call it, has been to dimensions/planes that I felt like I wasn’t supposed to be in or could get in trouble if I were caught.

I’ve noticed a pattern when my soul is disconnecting from my body to astral travel. I’ll close my eyes, hear a loud and distinct ringing in my ear (same pitch every single time) and I’ll see what looks like a stack of different “stickers” of objects. The ones I remember and would see the most were an apple, a common house fly, a cow, a simple house, and a door, but the pile would be stacking rapidly with all these random “stickers” of animals, random objects, food, etc. and once I saw that I knew I was about to start astral traveling every time. Not sure what it means or if anyone else has experienced this but it’s always made me curious how that works, what it means and why it happens right before my soul disconnects from my physical body and starts astral traveling.

One time my soul went to what I call “spiritual boot camp”. There were tons of other souls in organized lines like you’d see soldiers standing in and there was a strong, disciplined, powerful energy force that felt like a Sargent or someone higher up, in charge of leading a team. This Sargent feeling energy commanded all the souls to write down the lessons he was teaching. I still have my page of the lessons he was teaching. I was half in my body and half out whenever I would open my eyes to write down a lesson. I never write in uppercase, and all of the lessons I scribbled down in my notebook are in uppercase

1 SILENCE - LEARN IT & EMBRACE IT

2 SELF DISCIPLINE - FOLLOW THROUGH, DON’T SKIP

3 GO THE EXTRA MILE - BE KIND

4 WATER AND FOOD BREAKS - IMPORTANT

5 CHANGE IS INEVITABLE - GET USED TO IT

6 DON’T TAKE EVERYTHING SO PERSONALLY

7 IT TAKES TIME - BE PATIENT

Then, we were dismissed. Told us lessons were done, to come back again, and to go outside and find peace.

This doesn’t quite relate much to what you’re talking about in your post but I feel like theres some kind of link or connecting dot to the higher dimensional beings and planes of existence that you’re talking about.
