I had an acid (orange sunshine) experience in my youth, and I didn't like it a bit.
I think the reason being that I was alone and forgot what I had taken, where I was, who I was, etc. which scared me.
Also, I probably did it for the wrong reasons. It was the thing to do at the time to buck authority.
Hence I swore off chemicals, and only smoke bud occasionally.

However, I am extremely attracted to DMT.
I am currently seriously considering getting Mimosa Hostilis and extracting.
When I was on acid, my perceptions of the external world were distorted, eg.
everything looked like plasticine, the wallpaper was blooming, etc.
The hallucinations were external, as if the chemical affected the part of my brain involving the senses.
But from what I have been reading, DMT is wholly an internal experience.
Is this true?
Being a spirtually motivated person, I think this is what attracts me.

Also many years ago, during a group meditation I had a vision that impacted me, and that I have very often tried to reproduce but to no avail.
I suddenly saw pure black, like I'd never seen before. Then neon green square outlines were coming toward me -small, getting larger, then passing around/past me- with more squares continually coming through more squares. It also was synchronistic with my breathing. I don't know how long this lasted.
My very first reaction was fear for a split second, because it was such a surprise I think. Then immediately it vanished, and I was calm and in awe of the show.
I was an observer, and I was thinking something to the effect, "Wow, this is amazing, wait until I tell John." -my partner at the time, who was also at the meditation.

Now, I described this experience to someone recently and they said, "Oh, that's DMT."
Was my pineal gland triggered somehow to release DMT?
Does this sound like a DMT experience to you?
My goodness, if so, I want it again.
Hence my attraction to DMT.

But from what you wrote, I think you'd love DMT

A dmt experience can be so many things . To describe it
As an exclusive interior experience Ian't exactly right as
There are so many flavors of experience. It's beyond words most of the time
The one thing that stands out is one's almost complete
Lucidity and clear comprehension during most journeying.
It's as if a completely new set of rules suddenly replaced
Everything known up to that moment. And there you are looking at
Unimaginable things instantly .

At low doses DMT can mimmick meditational/prayer like states of absorption, at higher doses there's nothing like it, nothing can prepare you for it.

I think whoever told you 'oh thats DMT' is quite misunderstood to say that, thats like assuming any inner vision you can ever possibly have is triggered by endogenous DMT, something not at all proven.

I really would not recommend going into a DMT trip looking to repeat any past experience, it may feel familiar when you're in hyperspace, but it's not like you could ever expect it.

DMT can be both internal and external. It can reshape the world around you for the duration of the experience and it can project anything you see with your eyes closed onto the surfaces of the world around you. If you're looking for a light show with geometry then this may be the substance for you though

Woa there cowboy.

Heed caution, DMT is a lot more mentally involved then you would imagine, emotionally too.
It can really shake you, even good experiences can be scary intense at times.
There are reasons why it is revered throughout the ages.

DMT might be geometric and light based visually one time, another it may be photo-realistic immersive experience in the shoes of another species on another planet.
Its just that infinitely bizarre and unimaginable.
Its hard to explain but i think you should realize how unfathomably convincing some of the experiences may feel.
Trying to describe even one experience of DMT is like trying to catch water,
and explaining to people the cautions and the power of it all may be fruitless.

Perhaps someone may not understand until they have tried it, but if all you want is a light show you may very well get your socks knocked off.

There are inerrant risks with something so mentally shattering. While a great many people find it therapeutic and spiritually healing, those same people will admit that scares can be quite powerful.
The idea is to use these difficult experiences for what they are... symptoms of things being perhaps not ideal internally often. Perhaps lessons other times.

The ability to let go of fear, truly is something many people try to do. It may be an act held in high regard when in regards to psychedelics or DMT specifically, and is a mighty fine path out of a dark situation during trips.

This can help to know if one catches a fright, but is general advice outside the realms of fear. Or rather in various levels across the spectrum. Letting go of negative thoughts, habits and unnecessary mental baggage. Forgiving people.

Lots of this stuff has been said before in various places, times and religions. It seems to fit in well with the psychedelic experience.

Wow i ramble on.

You're absolutely right. I've had some crazy emotional experiences with it as well as realistic ones. I certainly didn't think very thoroughly before posting that one. I realize it holds an enormous array of experiences and I realize there's more than I can imagine as well.
