I was observing a group of men stripping the clothes off several women. The group seemed to be preparing to engage in casual sex. I saw another man wearing a yellow cap over his erect genitals, and I could see yellow liquid covering his lips and pouring out of his mouth. I warned the people that a storm was coming and they should leave the area, but they ignored me and continued their acts. I then looked at the horizon, which turned black with storm clouds so dark that no light shone through. It looked terrifying. I warned the group again, but they ignored me. I left the area quickly for fear of the storm.
