Are you asking for links to the DMT sites or to stuff about Strassman? Well, I suppose I can do both. Though, from this point on per Woodstock's request I must ask that if you want to continue this discussion we take it to a new thread or to PMs.
If you actually read much about Strassman, you'll find that the reason he thought DMT might be involved in near-death experiences and dreams was just because of subjective similarities and because it does exist naturally in the human body. Not an absurd claim to make, but the experiences aren't really that similar. There are definitely similarities involved, but so are there with any other type of out-of-body experience.
So, first they tried to tackle the whole "it's made in the pineal gland" thing. I hate to quote from Wikipedia, but there's actually tons of source links in this paragraph so I'd rather just grab it as a whole than link to them individually.
Dimethyltryptamine - Wikipedia, the free encyclopedia
(click to get the sources, it's anchored to that section)

Those enzyme assays are performed either with a radiolabeled methyl donor like (14C-CH3)SAM to which known amounts of unlabeled substrates like tryptamine are added,[23] or with addition of a radiolabeled substrate like (14C)NMT to demonstrate in vivo formation.[6][26] As qualitative determination of the radioactively tagged product of the enzymatic reaction is sufficient to characterize INMT existence and activity (or lack of), analytical methods used in INMT assays aren't required to be as sensitive as those needed to directly detect and quantify the minute amounts of endogenously formed DMT (see DMT subsection below). The essentially qualitative method thin layer chromatography (TLC) was thus used in a vast majority of studies.[23] Also, robust evidence that INMT can catalyze transmethylation of tryptamine into NMT and DMT could be provided with reverse isotope dilution analysis coupled to mass spectrometry for rabbit[29][30] and human[31] lung during the early 1970s.
Selectivity rather than sensitivity proved to be an Achilles’ heel for some TLC methods with the discovery in 1974–1975 that incubating rat blood cells or brain tissue with (14C-CH3)SAM and NMT as substrate mostly yields tetrahydro-β-carboline derivatives,[6][23][32] and negligible amounts of DMT in brain tissue.[23] It is indeed simultaneously realized that the TLC methods used thus far in almost all published studies on INMT and DMT biosynthesis are incapable to resolve DMT from those tetrahydro-β-carbolines.[23] These findings are a blow for all previous claims of evidence of INMT activity and DMT biosynthesis in avian[33] and mammalian brain,[34][35] including in vivo,[36][37] as they all relied upon use of the problematic TLC methods:[23] their validity is doubted in replication studies that make use of improved TLC methods, and fail to evidence DMT-producing INMT activity in rat and human brain tissues.[38][39] Published in 1978, the last study attempting to evidence in vivo INMT activity and DMT production in brain (rat) with TLC methods finds biotransformation of radiolabeled tryptamine into DMT to be real but "insignificant".[40] Capability of the method used in this latter study to resolve DMT from tetrahydro-β-carbolines is questioned later.[6]
So that was a pretty big hit to the whole pineal gland theory in general, which both the dreams and near-death experience claims surrounded.
As for what else.... Well honestly, it's kind of hard to give sources to show that something doesn't have scientific backing lol. But that's the point, really.
I found this quote from an interview with him, haven't read the whole thing though.
131. Dr. Rick Strassman On Whether Psychedelic Drugs Prove We Are More Than Our Brain | Skeptiko - Science at the Tipping Point
Dr. Richard Strassman: So the whole issue of NDEs is interesting because I was actually anticipating a lot more of the classical kinds of near-death experiences in my volunteers than actually took place. I was speculating that the occurrence would be a lot more common because of some speculations that I had put forth about ability of stress-related release of DMT at the time of death. That’s purely speculative at this point but still I was able to marshal substantial evidence suggesting that DMT could possibly increase as a result of stress which occurs as you’re approaching death.
Note the underlined parts, the first showing that there were a statistically significant number of differences, and the second showing that he even refers to it as a theory. I have no idea where that last bit about DMT being released in stress comes from though because I've never heard that before, and there doesn't seem to be any source material on that page. I'd like to hear just where he got that from.
But, as aesthetic reminds us,
Strassman is a psychologist, not a scientist so you cant claim anything as proven fact or "scientific data" lol.
Personally, I think that's enough to cast a good deal of skepticism on to the whole thing, but if you want more links you can always ask me elsewhere.
As for the DMT sites.... The only one I've really thought about in a long time is dmt-nexus.me. I know there's ayahuasca.com too, but I can't remember how good it is.... Aside from that, try DMT areas on big forums in general, like drugs-forum.com, or just asking about DMT in educated places like bluelight.ru. I could go on but I don't want to get in trouble for posting too many drug links here lol. Like I said, PM me or something if you want more.
