Physical and mental change

Trances lead to various temporary mental changes:

• Narrowing of perception and attention
• either negative (fading out of real things) or positive hallucinations (imagining unreal things)
• Significantly reduced or increased memory capacity
• Altered perception of time (dilation or standstill)
• special feeling of control
• special emotionality

and physical changes:

• altered muscle tone (either rigidity or hyperactivity)
• involuntary movements (e.g. Carpenter effect)
• Lack of pain and sensation

There is no universal definition of trance. The above explanation of the term forms the lowest common denominator of various definitions.
