Dream interpretation? Any ideas?

I keep dreaming of escalators/travelators (bizarre I know), sometimes I dream, if its an escalator that its moving way too fast and I'm zooming to the bottom at speed, like that dropping sensation that usually wakes people up, except I dont wake up. Or last night it was the travelator things again, except they were on a slant & I was led on them going along...its a recurring thing! & it makes no sense to me! Anyone have any ideas??? Thanks <3
