Could you please tell me what the phrase "rock my world" means? Thanks

Just from my own perspective and opinion, I think that it means to do something in such a way to make a difference for people as far as getting out of some kind of rut in their way of thinking that they may have been in for a long time. Or, to do something so creative and innovative that no one else has ever thought of doing it that way.

If I think about it, I am sure that I could come up with more of my own personal definitions for the phrase.

Just my opinion. I'm sure that there could be many definitions for the phrase depending on the experiences of the person providing the definition. Hopefully, you will have more...

Is there a particular reason why you are asking the question, please?

Rock my world means like you or something really positively affect the persons life in a really upbeat sort of way.
