While SWIM hasn't tested a full breakthrough while lying down (been meaning to for a while)
He has tested CEVs on mushrooms, pharma, mescaline, caapi, datura, and a few others
While being upright and in a bright or at least not-dark room seems to produce the most immediate visions, they tend to be mostly geometric shapes and not vary a whole lot. Also they seem to need a higher dose than the next position
The best position for visions (on all vision-producing substances, for SWIM) is lying on your side and as dark as possible, though dim can work, pitch black seems best.
The reasoning seems to be that this position puts his mind in a pre-sleep state which is basically effortlessly wandering thoughts and eyes focused in one spot, not darting around.
While these visions generally take a bit to happen, especially on medium/high doses if he relaxes and focuses on his breath, the thoughts wander in with them very interesting visions.
Now when SWIM told his roommate about this he was like "when I lie down to go to sleep.... I go to sleep..." so maybe SWIM's weird like that, but it is the wandering thoughts and still eyes that seem to be the cause.
Example:
While coming down from smoking a medium dose (20mg) of white DMT, SWIM was down enough to no longer see visions in the light and in an upright position.
He laid on his side and pulled a blanket over his head. Within a minute thoughts of his job floated through his head, (he's a gymnastics coach) he though of 2 adorable sisters, Sadie and Mila,
he though "They are so adorable, I just want to eat them up" then a slightly blurry vision of a child came and a big head came and it bit off and devoured half of the child.
SWIM immediately open's his eyes and exclaimed "that was fucked up!"
The visions are sometimes related to the thoughts but sometimes they are completely different, but the weirdly unrelated visions lead more thoughts in turn making more visions.
SWIM was hoping that he could adapt this to bright areas and/or upright positions, but for him the slight visions and the light prevent his eyes from staying still and thoughts don't flow as well.
While on his side in the light the visions are much much less as well.
SWIM is a huge hard-head for visuals, he knows that for many they come much easier.
His brother has told him visuals he's seen and they shock him so much. On 3.5g of cubensis and 5g of syrian rue he told me he was in a store and the whole world became one big tracer. He was able to say "Mandy, lets get out of her, we need to leave" he was also able to walk out with her, reach into his pocket and give her some change.
For SWIM to have that many visuals he would have to be about 2x as high as is needed to not be able to move or speak.... he's been unable to move 3 times (orally that is, twice on pharma, once on LSD) and everything looked a little wavy with spots and speckle, enlarging and stretch, but nothing at all close to a tracer-world.
