Reminds me of some of the description given by those of Near Death Experience.
Example, you may hear the description of of a light so intense and bright that it is hard to believe a light that bright is possible, though - at the
same time - the bright light does not hurt at all to look directly at.
As far as what happened to you, I don't know at all. Can you be absolutely certain that the 'mary jane' didn't have some other, unidentified,
drug in it? Can you be 100% positive of that?
It is possible that the 'mary j' did have something in it you have never ingested before or since, because a similar experience has not happened to
you before or since.
Possibly the 'MJ' did contain something extra that interacted with the alcohol in your system at the time.
Can you be certain, 100% that this isn't the case? If you cannot be 100% certain, you may want to look into psychedelic/hallucinogenic*(sp?)
experiences and try to find something matching your experience there as well.
Also, have you ever considered a possible out-of-body/astral experience? It has certain characteristics that can be found in the descriptions of some
NDE's. NDE's also carry some similar characteristics to OBE's. Your answer may possibly be found by searching there.
You also indicate that you had never really 'prayed' in such a way as as during the moments just prior to this particular incident. Could your
stress level have been heightened? Could you have triggered a psychotic episode of some sort?
The combination of THC (with possible unidentified components), alcohol, a heightened stress level, and lowered inhibitions from a new activity (such
as praying and psychologically opening yourself up completely to an unknown force or entity) could have easily induced an experience like nothing you
have ever gone through or anything you have ever heard of before.
If you would like to experience something similar to this in a couple ways you described, I would recommend that you study a bit on the methods for
astral projection and out-of-body experience. These things are 100% real and can be manually induced through proper procedure and practice.
Below is a couple videos detailing a few methods that detail methods to induce an out-of-body-experience:

The following is an excerpt from a good resource for information on Lucid dreaming, which can be associated closely with OBE
SOURCE :
There are two basic categories of lucid dreams: DILD (Dream Induced Lucid Dream) and WILD (Wake Induced Lucid Dream). The key difference between
these two techniques is whether or not you have a period of dreamless sleep before the lucid dream (DILD), or whether you pass directly from the
waking state into the lucid dream (WILD).
Here is description of a couple different types of Lucid Dreaming, which may or may not contain similarities to you experience:
MILD (Mnemonically Induced Lucid Dream)
This technique was created by Dr. Steven LaBerge who wrote about it in his book Exploring the World of Lucid Dreaming. It can often overlap with
reality checking because the goal is to do a reality check in your dreams. Typically, though, this technique involves spending a little time every
night doing an affirmation or visualization that you will have a lucid dream as you fall asleep.
EILD (Externally Induced Lucid Dream)
This technique relies on some sort of external cue to help you get lucid as you are dreaming. The most famous of these is probably the NovaDreamer, a
device you would wear on your head which emits soft blinking lights that you will see in your sleep. Unfortunately, this equipment is hard to find and
is generally expensive. There are other devices and signals which are more cost-effective, such as vibrating alarms. These will work for you if you
are very familiar with your sleep cycles and will be able to accurately guess when you will be dreaming.
The astral and OBE experiences can be different for everyone, though many aspects are commonly described by majority percentage of individuals who are
lucky enough to successfully accomplish Astral-Travel/OBE.
You may find that your physical and mental reactions to a successful OBE closely resemble the experiences you've detailed.
It is possible that you may find very similar experiences detailed by others who undergone successful OBE's.
It seems the description of certain aspects which occurred during your episode most closely resemble a Near-Death-Experience (NDE). However, I do not
reccomend you try and achieve a successful NDE for obvious reason (

)
I am going to link you to a couple sites that have a massive amount of information and descriptions from individuals who have gone through many
successful OBE's and those lucky ones who have lived to remember a Near-Death-Experience (NDE)
If it doesn't answer your question entirely, I feel confident that you will find many instances described that closely resemble many details you
shared about your incredible experience.
