Uneased feelings

Okay, this happened to me last night and it gave me a real un-eased feeling.

I was asleep in my bed, and at 2:40 AM, I get a phone call, I was like "What the fuck o.o" so anyway, I picked it up, and it was a 1800-mumdad call, which is where someone can ring you and leave a message and you can accept it or not, in the message it was a girl crying saying "Can you please ring me back!".

Now the problems were, I don't have any credit on my phone to accept the call, and she didn't leave her name, and all the crying I couldn't work out who the voice belonged to.

So I layed there for the next 2 hours wondering if one of my friends was in trouble or not, if someone was going to die, and the only thing they could do was try and get in contact with me, but due to my lack of phone credit, that person could now be dead.

Anyway, if you guys have any stories such as, I would like to hear them.
