You only remember the ones where the plot goes totally off the rails, dialogue makes no sense, and acting is just bizarre. Whoever is writing this trash is chronically incapable of producing anything even remotely good. It’s either forgettably mediocre or experimental chaos and pure madness.
Probably not. When awake, your brain is processing real input from your sensory systems (sight, sound, smell, etc). When dreaming, your brain fabricates those inputs, essentially replaying the neural circuitry from the dark and quiet comfort of your bed. Even without forming long-term memories, reality will still obey the laws of physics and causality but dreams don’t have to.
