I had this dream...it was random don't ask me, I only remember it because it was so weird.

I don't know where on earth we were, but T-Rex's had taken over the surface world, causing Humans to move underground. We had air due to these huge Tubes that went up to the surface. However I was running late because I had stopped to get some Potatoes, So I was on my motorcycle with a sack of potatoes behind me, riding around this volcanoe thing with a giant T-Rex thing on top. And then I woke up...Most random dream I have ever had!
