Every Christian should be involved in the deliverance ministry in one form or another, especially if you're going on the mission field.
Definately. It sounds as though you're already somewhat comfortable with it.
I'm sure you know that we don't need titles for what we do in ministry -- Jesus said that Christians would be known for these things. And he sent His disciples out to do it all. Being equipped can mean many things, but at least prepare yourself in every way you can for plans you make, and dreams you follow.
You father's house would be something connected with you, in a traditional or overseeing role. Something you trust and associate yourself with.
I almost wonder if you are being called to minister within a group that you don't think needs ministering to. Working within your own denomination, or county, or heritage.
The fact that the dream makes you shudder should be enough reason to take it seriously. Take note of how each part of the dream made you feel, especially in dealing with your dad.
There are a few ways you could look at this:
1. Demonic forces trying to intimidate you in your dreams (making you feel guilt through association), and you able to knock them out in real life through rebuking in your sleep.
2. Symbolic and prophetic message, gradually preparing you and hinting at how you need to prepare and what stance to take
3. Extraordinaty fear dream
4. Correlation to something in real life
