Am disturbed by what I jus saw

The world was ending, like on the brink
It felt like it was, these things ion KNOW were eating people, snatching em UP but I never actually got a look at them but they sounded massive
But some of em were like regular size too I think because their screams were very high pitched
People were divided into these colonies or units
And on a computer terminal I saw them each getting wiped tf owt. One by one.

And we were the last one, but our unit was not scared I guess because we were hidden they were loud and am like they can hear you, be quiet

This man and woman were arguing
But really was weird to me was they had this area under the house to keep all the children if we were attacked
But was weird was there was a baby giraffe and panda down there too

It had its head outside a window and I just knew it wasn't going to end well for him
Then they came and I woke up
Almost like I returned from the future to the present
What does it MEAN???
