Imagine a world where sharks swim in the forest and somehow you find yourself lost in the wordswrite a story you would tell

I thought of this while I wrote sorry its short

Explanation:

I was walking in the woods looking for something I don't remember what it was. When I heard a sound like a tail behind me I turned around and saw a shark I screamed running how do sharks live in the forest I thought.  I wasn't look were I was going and ran into a lake filling in I went under and stayed there. loosing oxygen I have been under for a minute and a half. suddenly a hand pulled me up and out of the water. my lungs felt on fire. I could not breath when suddenly my eyes went black at the edge of my eyes and I passed out waking up to see a shark the size of a skyscraper on top of me I screamed pushing it off trying but failing.  I woke up suddenly realizing it was all a nightmare and none of it was real. I felt real I thought to myself.
