Difference between Pray for and pray over
In the Bible, the usage of "pray over" is unusual, occurring only once:
Is anyone among you sick? Let him call for the elders of the church, and let them pray over him, anointing him with oil in the name of the Lord. (James 5:14, NKJV)
The sense is where people pray to God on behalf of someone (who may be sick and might not be able to also pray).
This passage is the origin of the Roman Catholic sacrament of Extreme Unction:
So, unction refers to the act of anointing the sick, the oil used to anoint the sick AND the spiritual disposition and hoped for response to the anointing. The hope for the sacrament is to bring about the physical healing of the individual who receives it as a continuation of Christ’s healing ministry.

The difference between pray and pray over would be that the former is quite general and used often. The latter is used rarely, and when the one being prayed over is sick or incapacitated.
The character in the Atwood novel may have thought that being prayed over was scary because she did not want God to do what the Aunts were praying for. (I'm guessing that the Aunts were not praying for healing from sickness.)
