To the human body, time is relative to the amount of physical stimulation we receive. Imagine you wake up from your bed at 4:17. You fall back asleep and what feels like hours later, its only 4:20. This is because you are in sleep paralysis and your body is receiving less stimulation.
If you completely cover your eyes and ears for a few minutes, you start to hallucinate. See, our minds are addicted to stimulation, and when we dont get any, we make our own up.
After your body dies, your brain has 10 minutes of activity left approximately. With absolutely 0 stimulation, your mind will start to hallucinate, and because of the same lack of stimulation, your body could turn that ten minutes into what feels like days or even weeks or months or years. That sounds a lot like heaven, doesnt it?
