Weird night, help please?

Ok so i just cane inicial from school but thats not the point. At 3:40am this morning i just suddenly woke up and laid on my back. I tried to fall back asleep and because it was cold i had my blanket up to my neck so my whole body was covered. Then suddenly i felt a hand on the blanket on my upper arm, it lightly shaked it and i heard a teenage boys voice say my name. At first i didnt even completely realize it so i just answered with a tired "hmmm?" And then two secs later when i did realize it i quickly turned my head around to see if anyone was there but there was no one and then just to be sure i turned on the light but there was still no one! Ok i know peter pan is magical but why would he just wake me up and then i couldnt see him?
