Spirits Trying To Give Me Advice?

Alright, so in my last experience, I told you that I was just seeing the ghosts or spirits. Well, know I hear them, like they're giving me guidance and such. A lot of them are just helpful hints, but is there someone watching out and helping me?

Example One;

I was taking a Math test, and I was really stressing, trying to figure the answer out. Suddenly, there a was a voice in my ear, telling me the answer and to trust them. For a reason I do not know, I listened. When I got the test back, the answer was right!

Example Two;

I was with my boyfriend on a picnic table, and he had his arm around me, and I had my head on his chest. As he was leaning down to kiss me, a car alarm went off, and a voice said in my ear "check your teeth!" as he looked towards the car, I quickly picked at my teeth, to find that there was lettuce in my braces!

Example Three;

There's a boy in my class who just loves to annoy me, and one day he was behind me, and I didn't think anything of it, until the same voice from the past two said "turn to face him, he'll pull yours," I didn't know what it meant, so I turned around, to see Josh pulling girls bra straps and letting them hit them.

Example Four; I was walking home from the mall, and the sidewalk had bikers on it, so I was walking on the road, as far as I could be from traffic. I was walking with my head down, when I heard the voice say "get out of the way, it isn't your time!" before I felt something like a shove, but when I looked up, I was on the sidewalk and a truck had just went zooming past.

I don't know if this is just my instinct, or if someone is helping me? I'm wondering, and would like some help? Please and thank you.
