Was not sure where to post this. Is there software available to download text messages from other peoples phones? A Google search would make it appear that you can spy on other peoples text conversations, and phone log.

I am afraid I may have been a victim of this. I received a hidden number call with no answer on the other end. There were a few clicking noises, but nobody would answer my repeated "hello, who is this?" A few minutes later I received an anonymous text message that was related to a text message I had in my inbox.

Is this type of thing possible, or am I being paranoid?
