I don't know why i get the dreams but I wonder if it's because I'm looking for acceptance. For the record, I had a few dummies on & off through my teens & early 20's while I lived with my parents & would suck them in my room while they were downstairs & I would listen for any movement they made so that I could hide them in time. I used to suck them for a while every now & then when I went to bed but I would put them down the side of my bed before I fell asleep so that I didn't them risk being seen in the morning. To my knowledge they never knew, but I can't be sure.
