Fear of enlightenment
fear of liberation from 5 skandhas is normal for those who haven't studied Dhamma.  Buddha mentioned it in (Udana Sutta, 


  "There is the case where an uninstructed run-of-the-mill person ... falls into fear over what is not grounds for fear. There is fear for an uninstructed run-of-the-mill person [who thinks], 'It should not be, it should not occur to me; it will not be, it will not occur to me.' But an instructed disciple of the noble ones does not fall into fear over what is not grounds for fear. There is no fear for an instructed disciple of the noble ones [who thinks], 'It should not be, it should not occur to me; it will not be, it will not occur to me.'


Quite long sutta but it answers your question.
