I believe the Universe is absolutely teeming with (intelligent) life, but not all life is in the form we can see or recognize yet. However I think we will make great discoveries in this matter within the next 100 years which will turn our entire world view upside down, if we don't kill ourselves beforehand that is. I actually wouldn't be surprised if we are already being visited, studied and observed by more advanced forms of life, and that they're keeping a low profile on purpose.
Or perhaps 'we' have been visited, and studied by more advanced lifeforms tens of thousands of years ago, and modern man is the result of a little alien manipulation on a 'naturally evolving' ape species. Perhaps this is why modern man is alone in both his tendency and ability to exploit and detach himself from the environment which ultimately created him and sustains him.
This 'revelation' of being part alien came to me on a DMT trip. Although it seemed realer than real at the time, I don't know if its true or not. If it were true, how would we possibly know or 'proev' it, if this alien entity operated on a completely different plane of reality and time scale from what we can comprehend? Would a soldier ant in an ant colony in some university research station be able to even begin to fathom the existence of the teams of scientists who were responsible for ensuring the foundation of the ant colony (perhaps genetically engineered) or what their objectives might be? Of course not.
Sounds possible, people who claim to have been abducted or contacted by alien beings are saying a similar thing as you here. But yeah it's hard to proof unless those beings decide to make themselves visible to the public and give an open press conference to explain everything to us.
I've always felt that the reality bubble we humans live in and experience is only a small bubble within a much bigger reality we can't even begin to fathom (yet). Like a fish in the water can't even begin to comprehend things like planets, stars and galaxies maybe we can't even begin to comprehend other things that for other more advanced life forms seem pretty obvious. We humans are able to expand our own reality bubble though, like we used to know nothing about stars and galaxies either. Maybe one day things like telepathy and moving through other dimensions will be just as normal to us as is riding a car now.
I never used DMT myself but I do remember an LSD trip where I was convinced I had broken my own reality and I was stuck in my own personal hell forever. Time stopped being fluid and chronological and felt like a shattered piece of glass, I was constantly being flung back and forth in time and saw very quick sketches of what was going on around me but it happened really fast and I could make no logical sense of anything at the time. It was extremely confusing and disorienting, losing one's grip on reality like that is probably one of the worst things that can happen to a conscious person. Some of those quick sketches I remember seeing at the beginning of my trip actually happened somewhere at the end according to my friends who were with me at the time, and vice versa, it was all just a jumbled mess until I finally came out of it 2,5 hours later. This trip made me think about how consciousness and time are very closely connected, and how little we humans know about these things. Probably just as much as fish know about our sun and other galaxies.
I think you may have a point.
I sometimes (very rarely) experience déjà-vu, mostly when I have a period of lack of sleep.
However these cases of Déjà-vu are a bid weird. The first time I 'remember' something while I am in a sleep-like state, but probably not actually sleeping. However I try to make sense of these memories but I can't, because things happen and thoughts occur to me that can not possibly be my own thought and actions. For example once I had such a 'memory' from me sitting in a classroom, but I was not even going to school back than. Then, months or even years later when the first few 'scenes' of that memory happen I start to remember the whole scene (which usually lasts 5 to 20 seconds) and I can repeat word-by-word what happens, and I can even remember my own thoughts. And always it is exactly as I remembered it.
It's like I have been there before, but I really haven't.
Time does not appear to be truly linear, it's just how we normally experience it.
How I know that they aren't my own thoughts/actions
I think about things I have never heard of, or about persons I don't even know. (On one occasion I had thoughts about being in love with a person I have not ever met, and didn't know. I was confused, why I was having thoughts about a person I did not even know to exist? Right now I met that person though, a coupe of years ago actually, and indeed I experienced the same scene as I saw it before, but it only made sense the second time, they never make sense the first time).
I am hanging out with people I don't know as if I'm familiar with them.
I am thinking about concepts I don't even understand or know
Such things...
