I can create a sleep cycle for your fantasy race. Just give me: Whether it's a napping cycle or not. If you want your species to be very light, light, moderate, heavy, or very heavy sleepers. Any parasomnias you want them to have. Whether you want to give them Bako [snoring, drooling, and having a snot bubble] or not. Whether they have a snore-sealer gland or not, or even if they don't close one or both of their eyes when sleeping.
