I dont smoke extract, i have.. but not for years, I grow my own and just smoke the plain leaf...i find I can achieve full breakthrough off 2 or 3 large hits in succession very easily..
dont really remember the specifics of what i smoked as this was a dream(Inever actually ingested anything, it all happened in a dream), but i am sure it would have been just leaf..
I have also drank aya right before sleep, and very early in the morning as well, in low doses so I could still fall back asleap and it was very strange..ive was just thinking that maybe if i can get some beta carbolines going through my system it would extend and potentiate my own endogenous melatonin and pinoline..worth trying I guess..or maybe i will try smoking some rue half way through the night..
I have had one interesting experience with calea a few years ago, but only when i drank a large tea and smoked some in a joint right after.
Also not smoking cannabis for a few days always seems to grant vivid and strange gifts while sleeping:d
About the salvia thing, its funny how many people refuse to smoke my plain leaves cus they think its placebo, like they dont believe i am actually tripping..they're all wasting their money on some 40 times crap..
