It activates the same chemicals in your brain as cocaine! 
Well, yeah, there are only ~~three~~^[@Neuromancer49@midwest.social corrected me] a few neurotransmitters. That's not saying much.
You know what else activates those chemicals? Practically everything. When scientists breed "knockout" mice without dopamine, the mice just stand there until they die of thirst, because there is no reward for.... living.
It contains more germs than a toilet seat! 
Germs like moist surfaces. We don't want germs on our toilets, which is why we make them out of porcelain, which is hard, dry, non-porous, and easy to clean.
If it had more germs than your colon, then I would be concerned.
I am not super-well versed in Jung myself, but my general understanding is that God would be the prime-mover of things, while the gestalt is created by us existing and being conscious. Think less Christian mythos and more like how the Warp works in Warhammer 40k.
The gestalt doesn't have 'a plan' it is just the shared psychic world (literally this is where the idea of a psychic world comes from) that both is influenced by and influences conscious beings. Basically, enough humans are afraid of snakes that even humans that have no experience with snakes tell myths of snakes, because enough psychic energy has been generated by those that do, while it probably has more to do with all mammals originating from small burrowers and having an inherent fear of snakes was evolutionary beneficial, but that is evo-psych which is just as non-scientific. We just aren't sure why.
To be blunt, I am not arguing for the existence of the gestalt, I am arguing that the idea of the gestalt has been extremely influential to fictional, and especially science fictional writing, and is, along with Spiritualism, the basis of ideas such as telepathy and clairvoyance.
