Why Is this happening? (Please Read)?

In a few of my dreams they have taken place in certain locations i dont know where they are but a couple of times now the places ive dreamed of have turned up on the telly its happened like 4 times now once was when i was watching Mistresses and i saw that a place one of the characters went to was in my dream everything was exactly in the same place but i just thought it was a coincedence then it happened again in another programme i was watching and it happened again today on to buy or not to buy it was this lovely like countryside area with a steep hill bit and i walked down it in my dream which was a couple of months ago but is this one big coincedence or is their something else going on?
