Let me plants a few seeds for thought with you:
* You have many types of coma
* You have many types of head trauma
* It is not clear if DMT is produced in the pineal gland, there are even indications that this might not be possible at all
* There is no evidence at all that you dream because of endogenous DMT
* DMT in your body is broken down incredibly fast by both MAO-A (liver) and Cytochrome P450 (in your blood) enzymes, so that 'supply of DMT' of your theory will be broken down in hours (maybe even minutes?) instead of months
And please stop the cursing, it is not needed and certainly unwanted on the DMT-Nexus.
Kind regards,
The Traveler
