As a kid i had a hammock tent. LOVED it, until i was caught in a legit thunderstorm and woke up flipping because the top held more water than i weighed....that really really sucked because it takes a good bit to even wake up and understand that you flipped and the zipper is opposite of where it was when you went to sleep. Then of course, now that youre sleeping on the roof that is pooling with the downpour of rain.
For me now I'd love to try again but my knees would need support under them because if i slept lock kneed like a hammock will make you, there wouldn't be much hiking after that.
