Restless sleep

Last night I dreamed about snow. From DreamMoods.com:

Snow
To see snow in your dream, signifies your inhibitions, repressed/unexpressed emotions and feelings of frigidity. You need to release and express these emotions and inhibitions. You may also be feeling indifferent, alone and neglected. If the snow is melting then it suggests that you are acknowledging and releasing those emotions you have repressed. You are overcoming your fears and obstacles. If the snow is dirty, then it refers to a loss in innocence, impurity and uncleanness. Some aspect of yourself or situation has been tainted.

To dream that you are watching the snow fall, represents a clean start and a fresh, new perspective. It is indicative of spiritual peace and tranquility.

To dream that you are playing in the snow, indicates that you need to set some time for fun and relaxation.

To dream that you find something in the snow, suggests that you are exploring and accessing your unused potential, abilities, and talents. You have uncovered some hidden talent and ability within yourself. It may also indicate forgiving yourself or others.

In my dream, snow was falling, but it was keeping me from where I wanted to go.

DreamMoods.com was not much help on why Elvis, Reba MacIntyre and George Strait were there.
