Does anyone notice a difference in their dreams based on what's going on in the environment around you?

I slept with the TV still on Friday night, and I had an LD. My dreams were really vivid, and I woke up satisfied.

On Saturday night, I turned the TV off and slept with the laundry room light on (it's attached to my bedroom). My dreams were odd, blurry, and I woke up feeling unsettled.

Last night I decided to do an experiement and left my TV on. I had vivid dreams again, and woke up decently.

Anyone else notice a pattern like that?
