Considering that time in dreams does not run in conjunction with time in reality (one can fall asleep for half an hour and dream, whilst in the dream days, even weeks, can pass).
Do you reckon that when one dies, one enters a state of perpetual dreaming? Our brains outlive our bodies after all (albeit by a matter of minutes in 'real-time').
If so does this mean that the Lucid Dreamer has the power to create his/her own afterlife?
