Sort of, I guess... I used to sleep with a blue, red or green lightbulb in my lamp when I was little, then when I got older, I grew accostumed to falling asleep with the TV on (I miss those days... I was in elementary school, so sleep meant NOTHING!! MUAHAHAHA!!!!!).
After that, yeah, like Twister, I have LED clocks or VCRs which give my room a dull glow. It doesn't really make the entire room bright, but tis my beacon for the morning! If I don't see the clock, I dun wake up... I dun wake up, I dun go to school... I dun go to school, I actually get 8 hours of sleep and feel refreshed in the morning (or afternoon.... toe-mae-toe toe-mah-toe)
