Psychological dream interpretation, first introduced by Sigmund Freud, is not some quackery like traditional dream interpretation, but a complex procedure that only can be properly done by a professionally qualified psychoanalyst who spent years studying dream interpretation and other psychodiagnostic instruments.
My idea is starting a new online service of expert dream interpretation. It would be a web-page where anyone would post his/her nightdreams free, then these would be interpreted by professional psychologists and university psychology students, requesting all additional information necessary and guaranteeing confidentiality.
On the basis of interpretation some psychological correction and support could also be applied

I think this idea is pretty easy to make real, plus there is a big demand for such services online.
