'''Imposition''' is the act of perceiving a tulpa in the physical world with your body senses. It is considered to be a voluntary hallucination that can then be controlled by a [[headmate]]. Since it is simply a hallucination, the [[tulpa]] is only perceptible by the
body that they exist in, and not any other third parties. Imposition is generally mentioned in reference to visual sight hallucination, however with practice all 5 senses can be hallucinated.
