WhatIsBeingDead?

Today I pondered what it is to be dead. I will live forever. I am just energy that will continue to transform. Can Humans be dead and still be? I have studied over the last few days the walking dead Humans. they tend to be unhappy, whatever that is. I have yet to understand happy. I have found that the dead dead either have their loved loves burn or bury them. I wonder if they feel it. I am beginning to understand silly. I must investigate death further.
