"Seriously brain, what the hell?" A Thread For Weird Dreams and Nightmares

I'd like to figure out how to lucid dream, but first I have to have dreams that aren't complete blackness. I'm sure I am dreaming, but I can literally remember none of it but just a big black space.

A very common problem.
The only things you need to solve this are a notepad and a pen.
Dreams are usually gone within the first minute after waking up, but actively registering them in a notepad helps you:

A. Remember dreams more often in general (Brain training)
B. Keep a nice log of dreams you have had.

Once you remember multiple dreams every morning you can think about lucid dreaming. It sounds almost unachievable but it's pretty easy if you take a small amount of time for this each morning.

Edit:
Another dream I have had plenty of times (and no, NOT lucid. AGAIN.):
It is night and I stand at a T-intersection with a road sign with place names. I can't do a thing, only stand there. I can't properly read the names either.
