I was going up to my house and I did a levitation command (here is that command : /effect @e [dy=37] levitation 1 5 true). The first time I went up I missed stepping onto the the land, bobbed down, and then I went back up and stepped out of the levitation "field" and I took damage. When I re-tried it bobbing two times before stepping out then I died and it said ([MY USERNAME] fell from a high place).
