intensity and its physical response

[repus11]

SWIM has been smoking hydroponic weed multiple times daily for a year and a half, since he got into college. About 4 months in he experienced an intense explosional feeling in his head immediately after hitting a bong, followed by balls of pressure moving around mainly in his head and face. It felt like it might rupture something internally at any moment, and having experienced nothing like it before, he was intensely anxious. It lasted for the duration of the high, and there were no symptoms afterwards. To this day, no sensation or peak anxiety matched the feelings of that night.

Four months following this, SWIM tries DXM. The day after he comes down from the trip, he smokes and experiences a minor, less intense episode of what I just finished describing. Throughout the next six months, he experiences on and offs with these sensations, and since he cannot describe them very well, or where they might be coming from, he does not see a doctor. At this time, he also starts experiencing social anxiety and auditory hallucination, and takes Paxil for two months, before deciding that the answer was not in prescription meds. At this time he gets into metaphysics and Buddhism, and is meditating, usually after toking up. Three months following this (during which time he tripped for the first through fifth time on LSD) he tells me that he has developed frequent muscle twitches, and that they are making him uneasy. He mentions Kundalini and anxiety as a source for these problems, and that yoga might cure it. He also said that when his mind begins to wander and then sharpen intensely on some idea/event/dream, that is when the physical reaction of twitching or jerking peak. With no yoga teachers in the area, he decides to cut back on the weed and psychedelics, and decides on breathing techniques to ease the anxiety/arousal.

It is now about two years since he started smoking, and still has minor twitching on a daily basis, but he says that he knows how to remain calm, so he is ruling out anxiety as a cause. SWIM says that when his mind drifts, that it pulls him unexpectantly out of focus of his surroundings, and that his thoughts take on an all at once vision of clarity, or seeing things from multiple sides. It seems like he is having mystical experiences and and that some sort of subconscious process is opposing them, hence the twitches. He said that everything he experiences during these moments (sensation on the temples always starting on the left side, full-body nervous system rushes) is epilepsy-esque, but he feels like he remains mostly conscious.

I should also mention that he is without a doubt a psychonaut, very into chakras, 2012, philosophy and the like, and has also had at least 6 minor head injuries, all requiring 2 stitches apiece.

I wanted to know if anyone knows anyone with similar experience so I could give him any advice or direction, because he has an intense but reserved and alienated personality.
