An awakening experience reveals that all there IS is awake presence - no-thing and every-thing simultaneously. So therefore, the 'personality' is effectively a 'ghost construct' revealed to have no real substance. However, unless the conditioned programming (that effectively makes up this ghost construct) is explored deeply and seen for what it is, the invisible effects of this 'non-existent (!)' construct will continue to contaminate - and therefore 'haunt' all manner of experience.
