> isn't a medically recognised condition.

Personally I wouldn't describe it as a medical condition, it has no adverse effects at all, and I wouldn't want to "cure" it. Whats wrong with having a spectrum from no imagery to vivid imagery and accepting that mentally healthy people can be anywhere on that spectrum? This tendency to classify any variation between people as normal or abnormal is completely unnecessary in this case.

PS not meant as a personal attack at all :)
