I have been living in my house for 7 years now and for all the time I have been living here I have allways exsperanced strange things sutch as I live in a detached house and at night my landing and bathrooms floor bords creek and thump some times all the lights in the house will flash on and off at once I also have 2 dogs and on multipale ocations they will start barking or whimmpering at walls or pictures I don't have a clue what's going on and I just wanted to know if it could be supernatural or if I'm just being paranyoid? (sorry about the spelling)
