Hiya there!

As to the lights - faulty electrical things in dreams is VERY common. Myself, I think that it;s to do with the fact that information about man-manufactured objects is stored in a different part of the brain to that which recognises natural objects, faces, and places. But that's just my theory. Not sure what you can do to make electrics work though. I think you just have to put up with it, or just very strongly EXPECT them to work and don'tr get frustrated when they don't.

As to flying - Sorry, I can't help there, but you should check out the lovely Amethyst Star's lovely Dream Flying Tutorial. the few times I've decided to try and fly in lucids, I've done so fairly easily. But for me, it's easier the less vivid a ld is. It's easiest when I have "groggy" LDs. But, if you work your way up to it, and more importantly, EXPECT to be able to fly, you'll get there.

Hope that helps, ciao!
