Thanks for answers
I did some research today on Internet and don`t think this is issue related to hermetism but rather an attempt to resocialise people who have some learning or mental disorder.

Reading more about Indigo people (or Indigo children) I realised that I have a lot of characteristic they are suposedt to have, but those are also common for almost all people with some mental disorder/illnes - high level of sensitivity, impulsivity, inteligence, empathy, negative attitude toword social rules etc.

Thing which is also common for Indigos (and I don`t have it ) is hearing voices and comunicating with aliens.

However, this is very interesting theory and I am still very curious who launched it and why.
