Predicting The Future?

Thank you for reading my story this is the first time I have posted and looking for some advice. I am 17 and have never really had any experiences like this before just to begin; I fainted a few months back for the first time and now I am able to do the following things.

Recently I have been able to tell when something happens before it actually happens, or I will say something and then it will happen. For example a few times I have been waiting for the bus with my friend and said "I wish it would hurry up." then the bus will pull up. Another time I was waiting for the bus home and a bus came but it wasn't the one I wanted. I said "I need the 545." and the bus changed to the 545 as soon as I said so which was really weird. I have had a few other experiences such as mentioning someone's name and them walking past or saying something's going to happen such as my dad coming home etc. I have had nothing like this happen before until the last few months apart from one time when I was really little I can't remember it very well I don't even know if it was real or a dream but when I was younger I fell over and instead of landing flat on my face I floated a few inches above the ground and felt someone gripping my shoulders as if to save me from falling that has never happened again but I always feel like someone is with me and protecting me from things. The first time I managed to predict something was when I knew my sister was going to hurt herself before she actually did and then after that something has happened everyday it changes on how many times a day but it's always at least once.

I am just confused on exactly what is going on do I have some sort of gift or is it just coincidence? Does anyone else have anything like this?

I will look forward to any suggestion people have and thank you in advance for the help.
