Thank you for sharing your dream with us. You will be surprised by my interpretation, as the symbols in your dream are primarily about you and not necessarily related to all the people you saw in your dream.
In fact, dreaming of an old partner symbolizes your fear of making bad choices that would lead to major upheavals in your life.
Your subconscious mind is trying to provide you with the wisdom you need to become more mature.
The elevator symbolizes the ups and downs of your life. But for this dream, you need to be particularly attentive to that unconscious fear that concerns your sexuality as well as your difficulty in abandoning yourself completely in the arms of your soul mate.
This can generate an inner fear in you which does not allow you to reach a total pleasure and fulfillment.
You try to frighten your partner, this indicates a form of aggressiveness towards your entourage. Your subconscious invites you to channel your emotions in certain situations.
This chubby man symbolizes a mental laziness which sometimes tends to invade you. Therefore, it limits your possibilities in front of all that you can obtain in the life.
This is the reason why you have seen this door of exit, which symbolizes new opportunities which are offered to you, but also the achievement of all your wishes.
However, be careful because the discomfort you felt symbolizes a health problem that you may face. You must therefore take care of yourself.
Finally, the lady who speaks to you with an irritated tone symbolizes a dissatisfaction with your evolution. Your subconscious mind invites you to practice gratitude for what you already have.
