It doesn't quite make sense to create a taxonomy of hypnotic phenomena unless one intends to classify the experiences that are usually aimed for in the hypnotic tradition.

Such a classification can be the ideodynamic model as proposed by Erickson:

• Ideo-cognitive
• Ideo-affective or emotive
• Ideo-motor
• Ideo-sensory

However, a closer look belies that this turns out to be a taxonomy of experience. Understanding the hypnotic tradition within the context of phenomenological control, therefore, allows us a broader understanding and context of such distinctions.

However, phenomena's sought after by hypnotists and the methods they go by allowing a deeper understanding of the ways experience is modulated and created.

Some common ones are:

• Time distortion
  
• Regression/revivification
  
• Ideo-motor response (IMR) & Automatic writing
  
• Dissociation
• Absorbtion
  
• Analgesia/anaesthesia
  
• Amnesia/hypermnesia
  
• HFO
  
• Kinesthetic hallucination
  
• Non-volition
  
• Identity logics
