The universe must be made of nothing but energy. Every atom is just a piece of energy moulded into an atomic structure. The universe seems physical because we translate that energy into physicality. It is still though just energy. This means that your body and mind is just energy formed into a specific type of energy pattern. It is energy turned into a form of art. That being said, your conscious awareness is therefore the universe itself becoming conscious and aware. It's the universal energy field taking shape and thinking. So on that basis, your awareness is the universal energy pattern focusing itself through one particular medium (a human form). Once that Human form ceases to be, the energy does not disappear because energy cannot be destroyed. Electrons within the human brain stop firing physically but the actual energy pattern of the mind itself is not destroyed, the atoms/energy still exists. I therefore posit that when a conscious being dies it does no cease to be, it's awareness goes from being Human and expands it's awareness back into the universal energy field, an obviously self aware field of energy that is sustaining the universes atomic structure and laws.
