Yawning a specifically psilocybin side effect?

^Well, yawning is always contagious- even apparently between humans and some apes, and vice versa- but not sheep though-or other animals-but why it happens and why it is contagious I have no idea. Though serotonergics always make me yawn...
 
Same for myself....

I find myself yawning an awful lot on any tryptamine, but never on a phenethylamine
 
I get jaw-wrenching yawns at the end side of mushy trips, which always function to notify me when it's time to stop staring at walls and go to sleep.
 
I find that trytamine induced yawns are different to normal yawns & I can distinguish them one from another.

I reckon it's time to sleep when the trypt yawns have died down & the proper yawn peeps it's head in the door.

This thread is making me sleepy
 
I yawn like mad on the comeup of mushrooms and lsd, they are always very distinct yawns.. my jaw feels weird afterwards for a bit, it's a very strange feeling. After the comeup, I may yawn, but they aren't distinct enough for me to remember.
 
Yes, I can remember a fair bit of yawning on Mushrooms. Always set off a bit of a mindfuck too. Why am I yawning?! I'm tripping balls, this isn't boring! Do I want it to be boring? Am I generally not interested in these effects at all? What are my friends thinking, watching me yawn in this really altered state? Do they think I want it to seem like I'm bored and not really tripping hard? Fucking psychedelics...Lol.

I think the reason yawning is contagious is because we have mirror neurons. Basically we try and copy what other people are doing, because it makes us look more empathetic and connect socially with other people. Or at least i guess what they're supposed to do.

I also yawned a lot during my last MDMA experience. It was very clean, and almost tiring during most of the trip. But since it's not a tryptamine i guess that's neither here nor there....

however, i do remember yawning on the come-up of mushrooms. a lot more so on the come-up than on the come-down. I agree with Durim, they're strange yawns. Because you get a sudden urge to yawn, and then you do, but it's not quite satisfying. Sorta like when you yawn, but you wanna do it again to get a "good" yawn out there.
 
I love yawning, it just feels so good. Tryptamine yawns are even better but I have to tell people I'm not yawning because I am bored--I just enjoy it!

Any kind of warm, fuzzy, sleepy feeling is right up my alley and that's why I have always avoided opiates and benzos, they would be too tempting.
 
on the note of mirror neurons it might have been a survival mechanism with yawning, to get oxygen to us better. maybe the ones that didnt catch on died.
 
I love that feeling of yawning on mushrooms ....first i feel the energy building up...then its that magical release of a yawn...my eyes flash to the side then my mouth gapes and it locks me in a trance...nothing but beautiful geometric archetypes and DNA floating in my perceptive view of consciousness...i need some more :)
 
I must have yawned 5x skimming through this thread. I yawn almost out of control on most serotonergics, at least all that come to mind. I also always yawn, unless I had yawned within a min, every time I hear the word "yawn", I see someone yawn, or I see my dog yawn.
 
mm i've had a few incidents of yawning, more or less the world just seems so ediable to me that I drool and lick my mouth a lot. haha.
 
Yes, especially mushrooms as many other people in this thread have noted! It's always while I'm coming up and peaking that they are the most intense... and they feel so other-worldly and strange! Very distincts from a normal yawn...

Yeah, but the multi-range of behaviours that we don't unconconciously imitate kinda makes that redundant. Though I have heard that empathy thingo too....And yes, I have yawned several times during this thread.

Yawn.
 
Any one got some logistics on this?

You could be interested by this paper :

Hallucinogens with 5HT-agonist properties, including d-lysergic acid diethylamide (LSD) and N,N-dimethyltryptamine (DMT), have also been reported to modulate motor neuron activity. DMT elicits yawning in monkeys, and these and other LSD-like hallucinogens have been reported to produce increased frequencies of yawning in cats; data on this subject have been published only for the 5HT agonist 5-methoxy-N,N-dimethyltryptamine.

During studies of the specificity of a cat behavior model for hallucinogens, I observed that LSD elicited a high frequency of yawning. Since LSD is a potent serotonergic agent which also possesses dopaminergic properties, and since both 5HT and DA have been implicated in yawning, I used LSD-eliciled yawning as a starting point for a study of the roles of serotonergic and dopaminergic mechanisms in the behavior. In addition to its relevance to the pharmacology of yawning and the behavioral pharmacology of LSD, the study was intended as a preliminary investigation of yawning as a behavioral index of serotonergic and dopaminergic properties of drugs. Since 5HT mechanisms appear to increase, and DA mechanisms decrease, the frequency of occurrence of yawning, drug-elicited yawning may provide a simple system for studying the interactions of serotonergic and dopaminergic drugs, or for investigating the concomitant expression of 5HT- and DA-related properties of a drug with -mixedeffects. For purposes of comparison, I also scored limb flicking, a well-studied feline behavior which is not obviously related to yawning, and is elicited by many drugs, including LSD and related hallucinogens.

When I opened this thread I yawned, and it's mid day! they can't be that contagious can they?
