I was in a room made up of a pure white tile, all but a small black rectangular outline in the back as I start walking towards it. My feet barely shuffling across the floors as they slowly become a carpet-like material. I approach the black outline as it appears to of been getting further away from me. I start to run. My heart racing as I feel the walls closing in on me, and my eyes making a blurry vision of my head hitting the floor as crowds cheer and my mother weeps, not for my death but because of the fact that my sister was crying for my death, and I snap out of the vision as I awaken, walking through life, becoming suspicious of those who I trust, doubting those who yesterday, were undoubted.And as I walk through the streets I see a book store, I walk through and see many memories, all from my mind, some of them I didn't even know happened, and others for when I'm older, when I turn around, I see a man in a brown trench coat through the windows of the store, then he pulls a pistol out, and walks in, "You've seen too much" he says before shooting me three times in the head, and I awaken in reality.
If someone can explain this to me, that'd be amazing
