So yeah, the thing is, every time I get lucid in a dream it’s night time outside. It’s never day. It’s really annoing cause it’s so dark everywhere. I’ve tried yelling “More light” but that hasn’t work. What should i do? (well ok, i’ve only had like 5 LD-s or so, but still…) Does anybody have the same problem?
Yea I had this, Try going somewhere diffrent, like phasing through a wall. You could end up somewhere diffrent where it is lighter.
Try fast forwarding the time or raise your arms pretending you are lifting up the sun.
Tell the sun to rise. If it doesn’t, ask it why. 
Awesome! 
Sorry, can’t come up with anything good, maybe painting a sun…
Fly up, and using a lighter ignite the sun.
You can do countless things, one of the big things though, is both believing, and knowing that whatever you do, will cause lightness.
Try spinning around next time, it might take you somewhere else where there is light.
Or make a bomb filled with daylight.
