I'll go with #5
Can't deal with bedbugs or living with someone I don't like. Can't go without smart phone or tablet or internet. Don't really care about the stuff in #4. So, just hope it's a friendly ghost (actually did live with one once).
.....Why would ANYONE pick 1? The rest are all things that can be dealt with, but Bedbugs? Those are worse than pretty much any other household pest, up to and including Cockroaches, because at least Cockroaches will not dine on your blood while you sleep.
I will not touch alcohol and I'm not a Dog person, so it'd be #5.
