Do shrooms make you yawn?

This thread made me yawn

I found it somewhat interesting ... sorry Gendorf, I'm new at this :P

i always thought that the yawns was the bodys way of getting fresh blood to the brain, so every yawn brings on the trip a stage deeper. i yawn so hard sometimes i get cramp in my jaw or under my chin from stretchin my mouth so wide open from the yawn an my eyes constantly water from it.

yawning has nothing to do with circulation or the brain in that way. It's your body's way of getting oxygen into your bloodstream because your breathing has been lowered, because you are tired or are on drugs.

Breathing is controlled by medulla oblongatta isn't it? And the way your body knows when to breath is excess levels of CO2 and less oxygen in your circulatory system.
Yawning is a way to get more oxygen into your system, not just your brain, but that is part of it, and it is initiated as a response by your brain because you basically have forgotten to take deep breaths enough times.
No, this shouldn't delve you into a deeper trip, your brain doesn't start operating on some new level with an influx of oxygen if I am not mistaken.

Yes mushrooms make me yawn like a mofo

but doesnt your blood charged with extra oxygen also carry the shroom jiuce to your brain an thats why one feels more out of it after each yawn or is it just the trip getting stronger regardless of yawning?
Ive found the same yawning thing happens on Hawaiian baby woodrose seeds too.
