The user can absorb/eat/steal dreams/nightmares of others, either storing them into some form, using them for various reasons (food, inspiration, power, etc.) or sharing/passing them on. The effects of having one's dreams stolen vary greatly. Victims of dream theft may become unable to sleep properly, lose their creativity or even go completely insane. In some cases, there may not be any side effects at all, particularly if the dream is merely being shared or copied rather than completely removed.
