Sharks will go to the bottom in shallow waters and just lie there, usually holed up under rocks or in caves. But no one's really sure if they're resting or if they're doing this for some other, as yet unknown, purpose. Yes, Sharks do sleep at night by resting itself on the seafloor as if it's lying on a bed.
It was once believed that all sharks had to swim constantly in order to breathe and could not sleep for more than a few minutes at a time. Oxygen-rich water flows through the gills during movement allowing the shark to breathe. While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
