I was worried for you when I first read. I am glad I have not had a dream like that.
Although, when I was doing fresh water I did wake up to a 140 gal where about 40 gal had leaked out on the floor from a leak that was not there when we went to bed. Luckily we have tile floor. Still it took us a couple of hours to get the all over the living room floor.
The good part is that is when I decided to switch to salt water. Ben loving the adventure ever since.
