A dream about eating ice cream has to do with sensual pleasures.
Eating ice cream in a dream is a sign that you are allowing yourself to accept pleasure into your life when you may have prevented yourself from doing so previously.
You may have relieved yourself of feelings of guilt.
A dream that you are serving ice cream to someone can mean that you want to give pleasure to others.
Eating ice cream is associated with youth, so a dream of eating ice cream can indicate a desire to return to the innocence of childhood.
Dreaming that ice cream is melting is a message that pleasure is fleeting. This can be interpreted to mean that you should enjoy sensual pleasures while you still can, or alternatively, that you should not let fleeting pleasures get in the way of long term goals.
Melting ice cream in a dream can also be symbol of disillusionment.
