I think i was abducted

My brother and i were driving in the back seat of my grandmahs car on march 4, at 7:30 pm. We had been driving for a few hours already, and i started to get a headache. My grandmah stopped the car, because me headache had become so bad, and i had to puke. While i was puking, i saw a bright purple, and then black, and then a blinding flash of light before i passed out. While i was out, i kept dreaming about voices in my head, telling me to relax, ant telling me to not be afraid, and telling me to sleep. I think i was out for a good 4 hours, and when i woke up, i was in bed, with a huge headache, and a giant bruise on my left leg, and another on my side. i have no idea what happenened, but from that day forward, i kept having weird dreams about flashes of light, and searing pains, and short images of what happened that night while i was out. Can't explain what happened
