You're not crazy - I've freaked people out with my "telepathic" abilities. I woke up knowing my mother just died even though she was in Canada and I was in North Africa. I've correctly guessed dates on coins and prices on clothes, and I've randomly commented on what people were thinking about even though they didn't think out loud. My best friend got completely freaked out by that.
And once, when my best friend was sleeping over, we were sharing the same bed. In my sleep, I dreamt she was asking me to wake her up. I woke up and shook her awake. She said "thank god you woke me up. I was having a bad nightmare and kept yelling (in my dream) for you to please wake me up."
I don't know if it's telepathy or just that I'm more attuned in some ways.
all this to say, I don't think you're crazy at all and i'm rather pleased actually to see you're somewhat like me in that regard.
