It is generally not a good idea to sleep with a gecko in your room. While geckos are generally harmless, they are wild animals and can carry diseases or parasites that can be harmful to humans. In addition, geckos are nocturnal animals and may be active and make noise at night, which can disrupt your sleep. If you want to keep a gecko as a pet, it is best to provide it with a suitable enclosure and keep it in a separate room from where you sleep. This will ensure the health and safety of both you and the gecko.
