i think this the tragedy of the human being, we are conscious that at the end we are going to die, and this is extremely frightening fact !!!!, that's why religion make sense in this regard, it has a comforting narrative, i just wished if it was true.
What is so frightening? Every time you go to sleep, you no longer have your normal consciousness. Do you also fear sleep?
I am not saying I am in a hurry to not wake up again but I certainly do not see anything to fear.
Why fear the nothing you see death as being?
