It is my lot in life that I don't have many sexy dreams and even being denied in chastity, I don't seem to dream about the lusts that occupy my mind during the day. I have recently (last two weeks) started having brief dreams about scenarios where a cage or my cage is part of the dream. I wouldn't call the dreams particularly sexy or stimulating but I do enjoy the memory when I wake up and realize the content of my dream. Is this a regular part of your sleep cycle? It has taken me 18 months in on/off chastity and now suddenly I've had three of these dreams.
I’m only about 5 months in (very off/on) and I’ve had several caged dreams. They really are something else! Not as much lately though, but I’ve been more off than on also.
For me it definitely depends on how frequently I'm locked. I've been locking for over ten years at this point. At the beginning I never had dreams where I was in chastity, but after a few years I did. For now, I'm at the point where if I'm being regularly locked my dreams have me locked. If I've been unlocked for a few days my dreams will usually be without me being locked.
