Nightmare! :/

I had a rather disturbing nightmare last night! It involved a little boy aged around 7-8 years old. He was always on his videocamera, recording random stuff etc, and he had two videos which I can remember seeing. One was of him playing about with some crabs and squids and having a laugh.
As a kid does at that age.
The second one was the worst ...
He was in a field, grass everywhere and it was really tall/long grass. He was talking away, not sure what he was saying but he was rambling on about something anyway.
Then random noises kept occuring in the background! He would turn around and check what it was, but nothing came of it... really eerie stuff!
The noises would gradually come closer and louder!
I could detect he was worried and scared. So was I, to be honest.
Then he finally went to check what was happening around him.
He wandered off... a couple of moments past then all of a sudden this loud screaming just came out of nowhere!! Really painful screaming! I was positive it was the boy. It went on for agesss.. around 5-10mins. I kept thinking some-THING got him... I had couldn't help but think that! Some kind of creature/monster! I really disturbed me!!!

I woke up and TRIED to forget about it but no joy soo far :/
I've been looking up on any interpretations of this kind of dream but nothing soo far. It's one of the worst dreams I've had in awhile. I just hope it's the last!
