Minecraft Realms Crash

When me and 3 other friends were playing on my friends Minecraft Realms server, all of a sudden, all of us but my one friend crashed. They all have had success rejoining the server, but when I join, I crash again, but i show up for a second on the server, when I join, my friends say that all signs dart at me and shoot in the air when i exit. Not only that, but all cakes fly into the air with them... I honestly feel like Herobrine... I'm scared :|
