I dreamed that an egg turned yellow four or five times after it was opened.

This should be a release from your heart. It shows that there is pressure in your heart, just like something hidden in an egg is broken, which shows that you are eager to get out of this state.

It can also be interpreted as having one's own potential, that is, the so-called other self, breaking the eggshell, indicating that your potential has been stimulated.

This is just my understanding and dream. Actually, don't take it too seriously.
