Thank you for sharing your dream with us. Please take everything that I share to the Holy Spirit as He Alone gives the accurate interpretation.
You might have done something rash (hives) that is causing you emotional pain or you are bearing the brunt of it/or guilt. God wants to encourage you and heal you in the midst of that unpleasurable/uncomfortable circumstance/event/state as per “Then a doctor (a male, in his white coat) came and I saw that I was in pain but for some reason I felt that the doctor knew I was not sick but rather it was my mind. In the dream I saw that we (the doctor and I) were lying on the floor.”
