I open my window and I hear crickets abbd cars planes etc is this ok if I am going to have a LD?
Sometime I find it works better because when I dream I can feel the night air on my skin and it always increases the lucidity.
But it all depends on how comfortable you feel doing it…
If it distracts you when you’re sleeping, shut the window, but if you find it helps for some reason, leave it open.
I would agree with Napoleon. If the open window distracts you from having a LD then shut it. It doesn’t matter if it’s open or not.
I would say it most depends on the technique you’re using. This could lead to some interesting WILD-ing, when we seem most able to make those synesthetic connections that lead to vivid dream senses. But in my personal case, because I use MILD and CALD, once I become lucid even the feel of my bed IRL can be distracting as I try to stay asleep.
However, never underestimate the placebo effect! Don’t let yourself think it’s a problem!
