rotten houses & chases.... help!!

Hi I'm a newbie here! I'm glad i found this forum.
i would like some help figuring out a recurring dream (Ive had recurring dreams since iwas little).
all my dreams these days have been about abandoned houses, temples, or even one was a hole in the ground). the houses or dwellings are all falling apart and so rotted, i have fell through the floor many times. sometimes there are secret passages or rooms that i find and that is fun, but the overwhelming feeling is of dread. in these dreams (all of them) someone is chasing me, be it the cops, a murderer, or just an unnamed something. i always wake up covered in sweat. there is terror and fear mostly, with a little wonder when i find a secret passage, or room, but it always ends up with someone trying to hurt me or catch me and I'm always afraid by the end of the dream... any help would be super!!!
