For probably years now, I've had dreams about masturbating. I'm in my mid-20s and haven't been sexually active in years, but I do masturbate on a regular basis. The weird part is that in my dreams, I'm usually really close to getting myself off before I'm interrupted by something - someone in the dream walks into the room, or tries to talk to me, or something. These people are never shocked to see what I'm doing, but they prevent me from finishing.
Does anyone with good dream interpretation know what this could mean? I doubt it's my subconscious trying to tell me I'm sexually deprived, because I do have a very satisfying solo sex life. I've thought maybe it was stress related somehow, but I'd really just love to hear other people's opinions on what it could mean.
