The thing is, this P.K. Entity is created without the person being aware of it, from negative feelings, stress or trauma that hasn’t been properly dealt with.
These “beings” are very dangerous if they are capable of gaining an awareness of it’s self. At this point it must create negativity in it’s environment by any means necessary to both gain power as well as survive. And it will unless you can rid the environment and yourself of the negativity that brought this creature into existence in the first place.
These entities can and will cause harm to any persons within it’s reach. These entities, once strong enough, can also trap human spirits to the property. P.K. Entities are VERY dangerous. When you suspect this may be a P.K. Manifestation it would be wise to contact a trusted medium to help you verify and remove this manifestation.
So no, Humans cannot create ghost only knock offs, so to speak.
