Exercise Room / Weight Room
To dream of an exercise room, or weight room represents your mindset being focused on improving or strengthening some area of your life. Trying to be the best you can be.
If you see evil people, people dressed in red, red objects, or red light in a weight room this symbolizes negative habits or thinking patterns that may be getting out of control. You may be increasing fear, dishonestly, or arrogance in some way.
