i remember seeing a shark when i went swimming back in the early 2010s

i remember i was pretty young when this happened idk the exact time, place or what age i was but i remember i kept walkin further & further out to sea until i fell off the dropoff which took me by surprise so i didnt have time to shut my eyes my buoyancy evened out with my density causing me to freefloat the water was blurry due to the medium the light was passing thru but tat didnt stop me from making out what was right infront of me as i saw what looked like a shark move to my left i was so scared i floated there & waited for the bastard to finish me off except my mum scooped me outta the water & i ran away screamin for years she continued to deny id seen a shark but ik what i saw
