I just want to know if doing so will harm my chances of having a lucid dream.
I dont think so, because i left mine on last night and had my first LD in a while! I have read that a little bit of light that peeks through your eyelids is actually good for lucid dreaming.
I know it usually leaks content into my dreams, and may sometimes get me into HI faster, but I’m not sure if it has a good or bad impact on lucidity. Perhaps, if the ads are too predictable, you can use them for mnemonic?
Well, the sound shouldnt be up loud though if you plan to leave it on because sounds tend to cause you to get startled and come out of the dream. (Happened to me this morning…
)
I’ve had a dream when my TV was on and it was all incorporated into the dream. Everything I heard was translated on the dream itself, but I didn’t realize I was dreaming until after I woke up and I still heard the characters XD.
You may get some more DS, it may wake you up because a loud noise startles you, or it may do nothing. I don’t see the harm but if you’re looking for benefit it still boils down to how aware you are.
It may actually augment your chances of having an LD. I sleep with music playing, and sometimes, I can hear the song playing enter the dream, which occasionally allows me to realize I’m dreaming.
That’s not to say that the music doesn’t wake me up somtimes either…
On the contrary, I’ve had LDs with music playing in my ears from headphones, that served as a dreamsign. I think the music was fainter in the dream. Also I think dialogues and such from TV can be incorporated in dreams.
