I elaborated a bit below. It's basically a combination that for some people, with the right dosage and the right weed, can trigger a complete loss of control as in a NDE, breakthrough, dimensional travel, etc... experience. For those type of people, at certain doses that vary from person to person you should treat LSD+weed as if you were going for something like a DMT/ayahuasca/whatever "breakthrough" trip.
It's not super well known in the community nowadays and people going for the "psychonautic" exploratory experience use other drugs, but mostly any psychedelic if you edge it or do the right amount will take you "there". To do it with LSD you need to take like, a lot, but the LSD dose that will break you through if you also smoke weed at certain moments of the trip, is way lower, like 1/2 or 1/4 of a usual "heroic" dose.
If your mind is ready or open enough for this type of experiences you need to be careful, also if you are prone to psychosis or dissociation. It can be done safely but you need someone taking care of you, and also maybe prepare with the right diet and stuff like that. Also if you are trying it by upping the dose slightly you also have to be careful, because LSD+weed sometimes has a "reverse tolerance". Like, after an intense experience let's say on 150ug + a dab, your actual LSD "tolerance" may go lower as you are more "sensitive" or "open", and if you up it a bit to see what happens you will trigger a very intense out of body experience.
The "danger" of something like that is that you are usually not aware that your mind can do it, so it's kinda scary and intense. You can read about it but it's like for example reading about stuff like mental disease or orgasm vs. actually experiencing it. The raw realism of whatever place you "go to" and the intensity of the stuff you feel or you "know" is happening or will happen is always mind-blowing. Even after you've been through it a couple times.
The dangers of exposing yourself to this kind of experiences is that sometimes you bring "feelings" or ideas back, that don't integrate well with your daily life without help. There's an ancient term in the community which is "chasing the dragon", which reflects some kind of long-term manic quest to visit or meet some kind of entity of place or state of mind that's like the "ultimate high". It's not like, a super bad thing to do, but it doesn't integrate well with the life of most people and is generally regarded as an unhealthy obsession.
As in body feelings or were you getting like severe paranoia or social anxiety? If it's body feelings meditation, a good diet, etc... helps, if you want to keep on doing it. If it's the other thing you just have to be very careful as you may loose control completely.
The reason to keep on doing it and learn how to deal with the body feelings it's because it's a very unique mind opening experience, only that it can be a bit too much. With the right set and setting and the right doses LSD+weed can be as "mind expanding" as ingesting DMT or a salvia breakthrough, or even wilder. If you don't have the right company it can be dangerous though as you will probably be very very very easy to influence, it's not uncommon to just hallucinate what other people tell you.
I’ve never heard this before; it seems like something I should know; respecfully, would you mind elaborating?
