Not Sure If I'm Psychic?

I'm not really sure if I'm psychic? I've have very odd experiences in the past four or so years.

My most recent experience was when I was speaking to my father, and for some reason, I told him his friend was dying, and then about two minutes later, he got a call, and that friend was in the hospital, almost dead!

I have had some smaller things happen as well, such as when I knew the exact time the school bell would ring (no watch). Or when I knew the exact number of threads in some item.

I have tried telling some people about these experiences, but then the experiences seem to stop. It's almost like something is trying to tell me keep it to myself? But then the experiences start again a couple months later.

I have had many other things happen like my first experience I wrote, but it's hard to remember them because it was a while ago.

I have had odd senses of deja-vu too. Sometimes I also think someone is going to say something (not randomly) then they do. I'm just a teen, so this stuff is kind of strange to me.

I've read articles about meditating and releasing negative energy, but I'm not really sure if it's safe?

Do you think I'm psychic? Is there some way to find out if I am? --cool-astronaut
