I suppose, for those who otherwise have no awareness of a "higher self" , the act of connecting with it during creative expression may be interpreted as contacting something "outside" one’s self.
In some case yes for sure...But for those with no consciousness about themselves , it is way easier to negate even external manifestation and even blocking them at the source ... Because of the respect at the cosmic scale for free will , nobody can be forced or coerced in a state he consider alienating for himself ...
This is why sleepwalker walk manipulated by less respecting forces in some cases... See the last 4 years of brainwashing ...
We can be manipulated to go down , but not to go higher , we must decide it ...
