Is considerable Schadenfreude normal?

If someone drops his laptop or drives his car against a stone while parking, I laugh mostly uncontrollably strong, which is usually negatively recorded (has cost me ne bloody nose) …

Is that normal? How can I fix something?

What exactly do you find so funny when other people suffer damage?

The question is; do you want to fix it?

You just have a sadistic streak. Is not really bad now.

The thing is, it makes me very uncomfortable and can't suppress it… Someone was badly hurt and I was the only one who laughed loudly… Then everyone looked at me, but I do not know why that happened to me.

Because you obviously enjoy the suffering of others. Is not bad for you, but can be a public problem.

But I understand you, that's hard to suppress.
