To dream of the rapture may represents a waking life situation that determines whether or not you deserve to feel good or like yourself. An outcome to a situation that indicates whether or not you were too selfish.
A coming may represent pressure you feel to be extra generous or decent. A one time opportunity to prove your decency or generosity.
To dream of being left behind in the represents preoccupation with feeling that you don’t deserve something. Jealousy that others get do something you never can. Fearing never being good enough or never having a second chance. Being embarrassed for selfishness.
