A description of the experience
Apparent Communication with Discarnate Entities - Induced by Dimethyltryptamine (DMT) - Peter Meyer SOURCE EROWID
In the 1950s and 60s some researchers experimented with tryptamine hallucinogens injected intramuscularly. The first to publish in English on this subject seems to have been the Hungarian investigator Stephen Szara, while working for the U.S. National Institute of Mental Health in Washington, DC. (For some reason most of the earliest researchers appear to have been Hungarians.) Szara published on DMT as early as 1956, and produced a series of at least 11 papers on the pharmacology of the Alkylated tryptamines during the next 11 years. …..
Szara administered 75 mg of DMT intramuscularly to himself and experienced intense visions. He established "that intramuscular injection of 50 to 60 mg of DMT brought about intense visual displays... within five minutes. These reached peak effects within a quarter of an hour, diminishing and then disappearing totally within half an hour... Subjects became catatonic or lost consciousness when given doses larger than 125 mg." (Stafford , p. 314)
