I woke up in water

down by the river, completely soaked. I woke up to the cold water on my back. looking up  from the bank of the river i saw two ropes on a tree and one cut by my feet. I ran my ass back to my house, covered about a mile in  6 minutes. I go in my room and i see my laptop with nothing but SP open, I have no idea what happened…I did take 500x salvia which was kinda a dumb ass mistake but im so clueless right now.
