Can a person in hypnosis, be hypnotized to forget everything that happened to them, in a hypnosis session?

A person cannot be made to permanently forget everything against their will through hypnosis. However, temporary amnesia for parts of a hypnosis session can occur if the person is receptive and the suggestion is given appropriately.

In most cases, memories return naturally over time or when prompted. Hypnosis does not erase memories; it can only influence recall temporarily, and the person remains in control throughout the process.
