To dream of a long wide hallway may indicate upcoming travel to an unfamiliar place. A dance hall suggests a new activity that you may find yourself enjoying more than you had anticipated. A hall with many doors implies life choices; make a note of colors and doors, as this may aid you in making the appropriate decision in coming days.
To dream of an amphitheater suggests that you are currently being closely watched or scrutinized. Rather than letting this overwhelm you, turn it around and use it to your advantage.
Dreaming you are in an amphitheater symbolizes a position of trust. Try not to let those close to you feel down.
