Warning Dream

So last night I had a dream that I got in my car knowing that it needed gas soon. I started driving and completely forgot about it. Once I remembered, I looked down and saw that the needle was on empty. EMPTY?!?! I thought. I never got a warning. No yellow dot. No dinging noise. Nothing. And now I have to search for a gas station. And hope I can make it there. Too late, I panicked.

I think this dream meant something.
