Should I be concerned?

So… a few months ago I went to Walmart to do the groceries with my mother. As soon as we went to the car to go and pack the groceries in, a random old lady and her daughter ( I guess) just came up to us. The woman was asking if we could give her some money. We said we didn’t have any more left as we spent it all on our groceries and that we were sorry. Then I don't know how this weird convo struck up between the old lady and I but she just started telling me that she could sense many people were jealous of me and that I needed to get a cleanse. Again, I don’t recall how this convo started as this was months ago and I decided to not give it much importance ever since. But I don't know, it was just all a weird experience for me and my mother who listened to the whole convo and I wonder if she is right or if she just crazy. I don't know, am I the only one who has had this type of weird encounters? what do y’all think?
Should I be concerned?
