Not a bad thing i did in a dream, but i came close ( i am a novice dreamer, just started frequent RC's a couple weeks ago.) from what i remember I was on a bed with this girl, who in real life i am extremely attracted to. Well in this dream she was begging for me and asking me to do the deed with her, but to me i got this super bad vibe from her in the dream and kept telling her to fuck off or leave me alone. And i distinctly remember briefly laughing in my head because "this must be a dream" but i didn't go lucid
