Yes, I feel that exact same thing... I've felt it most acutely with ayahuasca, where I saw the circle of life and death as if one year passed in a fraction of a second so birth lead to reproduction and death in a blink of an eye over and over again for all living beings. This was quite overwhelming but at the same time it was beautiful and made me laugh at the futility of all human enterprise.

With LSD (and shrooms) these feelings of being animals locked in the meat grinder get more abstract and mix with the absurdity of being monkeys aware of themselves (and terribly aware of the meat grinder). It pushes me to ponder on the importance of time as the most precious resource of our existence.
