Recurring dreams...

I'm sure most people have a particular dream that happens over and over again. I do too... but mine is very hard to describe. Mine is about something chasing me. But this 'something' is very hard to describe. The whole setting is very dark... like in an indoor maze or something. The thing that is chasing me is not something alive, it's more like an entity than anything actually. Usually in the form of a giant black boulder. Not the kind in Indiana Jones mind you... a boulder with a life of it's own that just keeps stalking me. You can feel the evil in it and the power is juggernaut like. Of course it never catches me but it is some pretty scary shit... Haven't had it in a while though.
