Entities can become attached to people. Not all entities are malicious — most are misguided, scared and confused. But whether an entity is malicious or not, their attachment is not natural and is a burden to the person they have attached themselves to. The best course of action is to remove the entity (and help it to move into another dimension to prevent its reattachment).
After a shamanic healing, people find themselves feeling lighter and happier. Without the entity’s heavy energy dragging them down, they have a new outlook on life.
