Dreaming of being at the dentist to have a filling put in and receiving too much anesthetic can symbolize feelings of being overwhelmed or numb in waking life. The dentist represents a figure of authority or someone who has control over your well-being. The filling represents a need to fill a void or fix a problem in your life. The anesthesia, which is meant to numb pain, can represent a desire to escape or avoid dealing with difficult emotions or situations. The fact that you can’t feel any part of your body in the dream may suggest a lack of control or feeling disconnected from your physical self. This dream may be a reflection of your current state of mind, where you may be feeling emotionally or mentally overwhelmed and seeking ways to numb or avoid these feelings. It could also be a warning to address any issues or problems in your life before they become too overwhelming to handle.
