Yes, i've had dreams of myself or someone else v*ing, but i can't say it occurs very frequently. I may dream about that 4 or 5 times in a year. But it doesn't change how it effects me as an emet. After a dream like that, i wake up feeling sick from it and the images usually stay in my head or hours or even days after the dream.
They can be horrible! I know! Usually a person's worse fear comes out in their dreams, like those who are scared of heights usually dream of falling from very high places..etc. So i'm not surprised that we emets dream of v*.
For God has not given us a spirit of fear; but of power and of love and of a sound mind. 2 Timothy 1:7
