Black Outs And Premonitions

I'm a thirteen year old and I'm really scared of the things that have been happening to me. This has been happening to me for about four or five years. I don't know what to do. So if you have any advice or any answers please tell me!

In the early years of these experiences I have had many premonitions but luckily, I have not seen anything terrible or anything that has deeply affected me. At first I just thought this was a phase or just something that randomly happened to people. But then they started to happen about 2-3 times a month. In the 3-4 years it settled down and they rarely happened to me. I have had some black outs. It's like darkness creeps until I can't see a thing. Then my legs give out and I fall to my knees. After this has happened I get a major headache but it only lasts for a minute or so.

Now in this past year things are different. I have seen shadows, orbs, and black mists. This has completely terrified me and I do not know what to do anymore. I do not want to tell my parents because, if this is something, I do not want to frighten them. The black outs are starting to happen occasionally and I see things over and over again.

Another strange things that have been happening to me is that I hear my name called out when I'm alone or when I'm with my parents but I always ask if they called. I have premonitions once or twice a month, and I can guess who calls our house but sometimes I guess wrong. So please if you have anything on what has been happening to me please comment.
