projection of your  memory(records in mind),senses outside you and the things we took from outside us.

just like others do it    clearing the memory to come back to the original just like cleaning body  

projection of information .   is it real (galactic wars ,etc....) those things have been ,so the memory and the attached energys exist still in global,collective mind so they have to be cleared. people who feel attacked or offended ,is it in our memory of all the expiriences we had .

so it is easy to trick people also with the projections like they are real outside them because the memory they have of real expiriences.
do they exist  , yes , but its not them who have to come down but we who have to lift ourselves up to their consciousness.
