Why do I have such terrible rolling luck?!

[Apocalypse]

My wife and I were playing LNOE the other night with a couple friends (us 2 playing 4 heroes vs. 2 zombie players) we had something like 3 rounds left on a supply run scenario and we're trying to get heroes back to the house and the one hero in the house out and away from the zombie horde that made their way in. Game progressed as follows: Jake (in the Manor/thunder dome) rolls 1 for movement. Searches instead for miracle item, fights a zombie and loses. Sheriff rolls 1 for movement, shoots and misses with shotgun, rolls out of ammo. Becky rolls 1 for movement, searches. Johnny rolls 1 for movement. Zombie player ended up with shambles, tide of the dead, or something along those lines and Zombie players win with more zed in the house than we can clear in time. I have never seen all heroes roll 1 on every single dice roll in a round. I suppose it happens to all of us from time to time
