Corrected entry: The bed is soaked with blood after Jason kills Sandra and Jeff, yet when Vicky comes into the room the white sheet on top is spotless.
Correction: There was, but it might have been too soon. We don't know how long since he killed Jeff and Sandra, so it might not have had time to soak through yet, not to mention that the sheet would have tented over Jason and probably didn't make contact with the blood. Point is, it's possible so the posted mistake isn't valid.
Correction: Both Jeff and Sandra were impaled on the bed. Jason couldn't have possibly laid over all of the blood obviously. And there was a lot! The sheets were completely soaked with blood and when you cover blood with another white sheet it will obviously soak through. When Vicky entered the room there was no blood in sight.
I also just watched this scene. Not only was Jason under the sheet, but Sandra's body was as well. Vicky even addresses her as she approaches the bed because you can see her hair on the pillow. The sheet on top of them would never make contact with the blood with both of them lying between it and the sheet.
Correction: This was already corrected once. Jason most likely took a clean sheet, lay on top of the blood, then put the clean sheet on him. He was simply tricking his next victim to come closer to strike. With Jason between the blood and the clean sheet, the blood wouldn't soak into the clean sheet.
