12 totally bizarre things that happen while you sleep?

While you sleep, your body undergoes fascinating changes, including sleep paralysis, where you may be unable to move or speak upon waking. Hypnic jerks, sudden muscle contractions, can jolt you awake just as you're falling asleep. Some people experience vivid dreams or even sleepwalking, acting out dreams without being aware. Additionally, sleep talking can lead to bizarre conversations, often incomprehensible or unrelated to reality.
