Hypnotic amnesia works through post-hypnotic suggestions, where the hypnotherapist instructs the client to forget about certain experiences or details after the session. This happens as the subconscious mind temporarily blocks access to specific memories or events, but these memories and events are still present. This process is reversible i.e., the memories can be retrieved by canceling the suggestion or by using specific cues such as pressing the thumb, tapping the client’s shoulder, or snapping fingers.
Hypnotic amnesia can be related to dissociation. This dissociation can make some information or memories unavailable to the conscious mind. These memories can be accessed by removing the block.
Hypnotic amnesia can reduce the activity of the frontal lobe by temporarily blocking the mind’s ability to consciously recall specific memories or events.
During hypnotic amnesia, the client is asked to focus on certain thoughts, feelings, emotions, or memories intensely. This makes other aspects go into the background. This intense amount of attention leads to selective forgetting. The client’s mind is so involved in the suggestions being given during that time, that other parts of the experience become unreachable, even though they are stored in the memory.
