You must be very gifted.
I found this piece of information on the net. I hope it helps.
Transfiguration - Some mediums have the ability to act as transfiguration mediums, where spirit are able along with the use of ectoplasm to adjust the facial features of the medium by means of an ectoplasmic mask. The transfiguration is often so complete that the person simulated appears to be actually present. (A lot of people get mixed up about transfiguration, & lean toward the belief that they have seen transfiguration, when in fact they have seen the spirit person moving close to an entranced person by means of clairvoyance. Remember if the transfiguration can not be seen by all present then it is not transfiguration)
