Can Feel A Strong Presence Near Me

We'll I suppose to start my first experience was when I was 13 I was in a semi dream state and saw my grandad on the end of my bed. He hadn't been sick and I heard the Next day that he had died. Next experience of anything unusual was 19 I had a bad feeling that something was going to happen. So I was real careful that day, I was driving real slow and a car crashed into me. I believe if I was going faster things would have been a lot worse. I also woke up one morning and my phone was ringing and I knew my other grandfather was dead before I answered, he had been sick though. Just lately though I can feel my brothers presence real strong in the house and strange things happening. Radio turning on blinds opened, but more so the presence. I also feel my two month old can feel or see his presence as he stares and smiles and a spot where I have felt him to be. There has been few other experience which I have been told was sleep paralysis, which I'm not sure of because both times it has happened I've felt a strong presence near me. My question is as I'm a little scared of some of the things which have being happening do I ignore them or try to communicate back. I honestly believe my brother is in the house the last few weeks. He died just over two years ago and this is the strongest I've felt his presence. Does he want me for something? If anyone has had any similar experiences I'd love to hear them. I've been to 3 fortune tellers but not a medium as I suppose I'm a little scared of a bad spirit coming near me. The last one I went to a year and half ago said my brothers presence was in the room but I couldn't feel it as strong as I can now.
