But I Didn't Eat Pizza

A few nights ago, I had a dream. I didn't think anything about it until the next day. And now it keeps bugging me. 

I was on a bike riding down a never-ending freeway, and there was nothing around me for miles. It was a super nice road, had lines, was paved, etc. (I must NOT have been in Mexico...)

 There was a bridge up ahead and past the bridge, far far away were the lights of a city. I was racing down this road going so extremely fast that I couldn't even move my fingers to press the brakes for fear of losing control.
I was aiming to cross the bridge, but all of a sudden a dead end appeared in front of me. There was a rest stop and an old man standing there. I remember being scared I wouldn't be able to slow down enough to turn around. But I did, and right when I did, I woke up. 

The only interpretation I could come up with:

I'm headed nowhere fast. 

At least that is what I would tell someone if they told me what I just told you. 

That, or they ate too much pizza the night before.
