We moved into our house nearly 2 years ago, it was great for a while but about a year after we moved in we started noticing that our youngest child was speaking to something in her room at night. Then one night while we were in bed we heard this scratching noise outside our bedroom door but as my fiancé went to investigate it suddenly stopped until he got into bed and it started again this must have happened over and over for around ten minutes then suddenly stopped. All was quiet for a bit after that then about a week later I was out with friends. Upon returning home my fiancé had said he heard some weird noises in our hall like someone banging on the closed doors. Whilst everyone was sleeping my fiancé got up to use the bathroom and heard a loud bang then a long scratch down the bathroom door!... Upon returning to bed he heard a bang on the cupboard door behind him. Once again all was quiet for a while until that is 4 days ago...
We were lying in bed when the cupboard door unlocked its self somehow and slid along around 4inches, The next night lots of banging noises were heard in our hall and what sounded like a child crawling along the wooden floor in our hall, then all of a sudden our son's bedroom door (which is stiff) slammed shut. No one was anywhere near it.
Last night we heard what sounded to us like a child running up the hall.
Please give as much advice as possible as to what could explain this as we have never experienced anything like this before and are unsure of the steps to take to get rid of it
