I can echo this sentiment, as a normally soft-spoken guy who was arrested while completely out of his mind on psilocybin. My perception of reality was utterly shattered; I thought I had died and that my mind was transported into a realm of eternal torture. I'll never forget the dread I experienced while being forced to the asphalt and handcuffed by police officers on the side of the road. They took me to a hospital where I believed the medical staff were preparing to physically mutilate me (keep in mind, I was handcuffed the entire time...I felt helpless). When a nurse asked my name and address, I just broke down and started bawling. Apparently they gave me a sedative, and I woke up later to find my family sitting around me crying.

Psychedelics have an amazing propensity for good, but they can also destroy you. Tread carefully.
