Strange Things Are Happening In Our Home.

 We have lived in our house for 3 years.I am married & have 4 children (ages 7,10,13,17).Strange things have been happening since we moved in,but lately they are getting worse & a lot more frequent.We hear things all the time.Our dogs are terrified of our daughters room & bark at nothing all the time at night when nothing is there (usually into the kitchen or hallway).The other night my husband & I went into the kitchen to get a drink (we had been in bed & all kids were sound alseep) & our microwave was running.It had all zeros on it & nothing was in it.I hear very loud noises coming from our daughter's room (right above mine) all the time when she's gone.When I go up there is nothing there.My children have all seen and/or heard things.Our daughter has horrible dreams every night & leaves her tv on all night w/ the volume very high so she can't hear the noises.I feel something shaking the end of my bed at nights & my son has had this happen to him when he once slept in our daughter's room.One time my husband & I were in bed watching tv & heard a huge noise in our living room (right next to our room) sounded like a tv or something fell.We ran out there & nothing had been moved & nobody was there.Tons & tons of other things have happened,but way too much to list here.Anyone else have these types of things happening?
