Get yourself some protection.
I've had mostly positive experiences with ghosts and spirits, but there was a period when I had very unsettling experiences. From that I learnt I had to protect myself and my home from negative forces. I started by using a cleansing on my home to rid it of all negative forces - especially my bedroom which housed the brunt of it. Afterwards the room was much lighter and a nice place to be in. My house and yard is protected by white light, from above it looks like a giant marquee covers the whole yard, I confirmed that only spirits who mean me good and love me can enter, those who mean me harm are excluded. One night I woke up feeling like I had to strengthen the bond, as soon as I did that I heard 2 large bangs on a neighbour's shed next to my bedroom.
My house is patrolled by Angels, they walk the perimeter and have been seen on 2 occasions. All you need to do is ask them.
I once walked into my bedroom, my husband was snoring on the bed and there was a man standing by my side of the bed. I gasped and he disappeared - honestly my next thought was "Thank God it was only a ghost". I know who the man is, we are related and he is my guardian spirit.
