weird dream

Yesterday when I was sleeping, I had a dream it was really weird.. And I woke up all sweaty..

The dream go's like this :

I was married with a guy, and we had I child together. The kid was only like 4-6 years old. But we had my father-in-law on visit. And he was staying with us, for a couple of days. Then one day, after I had taken a shower, I was only wearing my towel, my father-in-law, started looking at me.. kind of sexually. I didn't like that. I spoke to my husband about it, and he confronted his father. Then the his dad got a little weird, and started to follow us everywhere, and do weird things.
Another day, when I was just sitting in a room, my father-in-law, came into the room, and started talking and being weird and scary. I didn't want to be in the same room as him. I could hear that my husband was taking a shower, so I ran out to the bathroom, and knocked on the door and begged him to open it. He did. I got inside the bathroom. My husband wasn't showering, just standing with all his cloths on, and holding our son, while the water ran in the shower.
My father-in-law, was running after me, and he noticed that I had run into the bathroom. We quickly locked the door, but the father-in-law had done something with the lock, so we couldn't lock it. He was coming closer and closer, so i screamed to my husband that we had to push the door, so he wouldn't be able to open it. We did, and when his father came, he couldn't get in. We heard him walk into the room next to the bathroom. My husband was screaming to him "NO DAD! THIS IS MY BATHROOM! DAD THAT'S NOT THE WAY TO BREATH!!"
Then. Suddenly, the bathroom wall exploded, and me, my husband and our child died.

Then I woke up. Totally freaked out and sweaty!
