Most people believe that they will survive death, not all, but most. This is because they have identified who they are with the body and ultimately with the thought "I" or the personality, which was only created during the time you have been in the world accumulating the knowledge of who and what you are, by your tastes and traits and upbringing.
This short little video says it all. This is the "I" thought shouting out at the world that it will survive, hence the creation of a "heaven" where all the personalities that can't seem to get along in the world will some how miraculously get along in some other place after the body dies. But this is a lie that only those that would like to think that they don't have to die, believe in.
There actually is a Heaven, but you don't get to go there, you are already in IT. But that is a big leap.
In this world, what is born in this world, does not leave this world and that includes the body and the personality or "I" thought.
So sing and dance and play and laugh until that ball comes falling from the sky which will discontinue the "you" in this world. You can also begin to take the time to focus the attention on what wasn't born into this world, and doesn't die when the world ends, because the world is in IT, just like "you."
