ELI5: Why do people have crazy dreams when they fall asleep again after waking up in the morning?

First, this happens because you stimulate your conscious brain at a time you would normally be experiencing REM sleep. This leads to consciousness in dreams. Second, when you do return to sleep, you will dive straight into REM sleep from a conscious state, also inducing multiple dreams one after another.

You also have a far greater chance of becoming lucid after waking up then going back to sleep.
