13) Very unique, more unique (unique means one and only)

14) “If I was” instead of “If I were”

I was taught to say:
"If I was on fire, I would burn, but if I were you I would just ignore it."

The distinction is that being on fire is possible. My being you is not possible. Several years ago I tried to verify this usage but ended up just confused. What is your rule?
