I understand the concept of sex. Many, many have wandered into my dreams while in tantric trances.
It was always amusing, seeing the flash of fear on their opposites face as suddenly they died, hearts bursting from shock upon seeing even a fraction of my true form. Even better were the ones that didn't die, but left quite the mess. Drowning was the most oft-used method, I suppose due to some minor transference from my consciousness to theirs.
