Noise will absolutely wake me up, but ot doesn't influence my dreams at all if that's what you mean. If someone is moving in the kitchen or closer to my room or outside my window on the gravel, I just jolt awake immediately
I can hear in my sleep but when in deep sleep no. My brother always wakes me up talking to my sister with his loud voice !
Every sound will wake my up or any bit of light that comes in my room.
Sometimes I hear the cat meowing in my dream, and then I wake up and she’s meowing. But I don’t usually hear things when I’m sleeping, they usually wake me up.
