light-headedness

I tried to cook myself some lunch. Grilled cheese on bread with barbeque sauce is my student meal of choice at the moment. So I did as I usually did, I put the oven on fan grill (the one where you can actually shut the door whilst cook) to pre heat it. But then this gassy, smoky stuff was coming out from the oven. Bad news. So I turned the oven off. I just hope that there's nothing still coming out from the oven. But if someone finds me passed out in my house, that's why!
