Who can see patterns when they close their eyes tightly at night?

Most people. Squeezing the eyelids tightly shut puts pressure on the eyeballs. The pressure transmits to the retina (the film layer of the eye), which responds the only way it knows how - by telling the brain that it is seeing light. This is a normal response; however, exerting this much pressure on the eye for prolonged periods can potentially lead to vision problems.
