This is actually the source of unaddressed traumas and subconcious demons... Osho was a fraud guru and a dangerous man to listen to. Real darkness must be faced head on and known, with the help of trusted support and people to catch you when you fall.
Modern "Light work" is toxic positivity, real spirituality must have total awareness of the light AND the dark.
"No tree, it is said, can reach to heaven, unless it's roots reach down to hell" - Carl Jung
