Hearing things

Hi

I hope I am in the right place for this question.

I have never been a big believer in this sort of subject, but recently I have been hearing furniture moved about but only when I am in the bathroom, there is nobody else in the house and I have no neighbours. And I also hear someone running up the stairs very loudly with shoes on but there was nobody in the house. Also a couple of months ago when I was in the kitchen something grabbed my ankle and I had never jumped so high, even my kids looked a little worried when they saw my face. I am rather confused and wondering if this is something out of the ordinary. We have only been living in this house since September last year and it is only a couple of years old.

I was hoping somebody might be able to give me some answers.

I did have something else happen years ago but I thought these questions were enough for now.

Thanks
