There is nothing wrong with your dream, it is psychological entanglement and bedding.
In your dream, you begin to look back and feel your life experience, and go to the end of your life in your imagination. You start late, have a slow pace, and have no elite equipment (knowledge and skills may be your school stage or your own evil exhibition hall).
In your dream, although there was some resistance at first, it went smoothly, but in the later process, the pressure became heavier and heavier, and you finally reached a turning point in your life (maybe choosing a job, maybe changing careers), but the future left you confused and basically hopeless.
In your dream, you haven't struggled and gained yourself, but there is the end of your life ahead (maybe you are pessimistic at ordinary times). You don't want to arrive so early, so you will start to stop breathing under the pretext of fatigue.
