Be careful
You don't usually use ‘something’ as part of the object of a negative sentence. Don't say, for example, ‘We haven’t had something to eat'. You say ‘We haven’t had anything to eat'.

used in questions
In questions, you can use something or anything as part of the object. You use something when you are expecting the answer ‘yes’. For example, if you think I found something, you might ask ‘Did you find something?’ If you do not know whether I found something or not, you would ask ‘Did you find anything?’
Has something happened?
