My friend has had this thing for about the past few years now with the scenery of her dreams re-occuring but they are in different dreams. It happens with a lot of her dreams but there are a few different scenerys that she has.
Its like shes having different dreams happning in the same scenery's / background's / set's.
Shes also never seen any of these places in real life, but shes still seen them before inside her dreams.
