It already happened to me twice, I can normally access and play when people invite me to join they realms but after a while (in this case were three days), the terrain stops loading and I can't have interactions with any items. My friends tell me I get stuck even though in my computer, I am moving and trying to break things. When I try to break a block, for example, it looks like it broke but doesn't give it to me. They also don't make the noises they would normally make and my pets stare at the point where "I'm supposed to be" no matter how much I've already gotten out of there.

I already checked, it's not my internet connection.
