Journey, the setting of your dream in a gym can symbolize a place of transformation and self-improvement. Gyms are where people go to work on their physical health, but in dreams, they often represent the emotional and mental 'workouts' we are enduring. Crying in the gym could indicate that you are feeling a release of pent-up emotions or stress in an environment where you are pushing yourself to your limits. This may be tied to your feelings of frequently experiencing sadness and the pressures from recent major life changes like relocation and career shifts.
When the guy called your name and everyone in the gym turned towards you, it suggests feeling exposed or singled out in a vulnerable state. This public scrutiny might be related to your feelings of anxiety and the pressure to perform or meet expectations in your new environment or career. The fact that you ran away implies a desire to escape from these pressures and the fear of being judged or not meeting standards.
The guy following you can represent a persistent issue or challenge that you are trying to evade but cannot easily shake off. This could be linked to your diagnosed conditions, such as ADHD and eating disorders, which might feel like they are always 'chasing' you, even when you try to move past them.
Waking up from the dream at this point indicates that these feelings or issues are not fully resolved and continue to affect your subconscious mind.
