"Open" sessions?

Every reading I have ever done has been in person with specific questions or people in mind - BUT I did momentarily open up to do a reply to a thread and another person came flying in out of nowhere.

I think I may have found the person they needed the message to go to but now I feel like I have a line waiting.

I'm happy passing things along but I feel a little "naked" doing it. Essentially, I'm just automatic writing for whoever comes through, with my guide pulling them back if they get too intense but I almost feel like censoring myself - not because I think I'm wrong but because of the fear that I'm wrong.

Has anyone with more experience gone through that feeling and how did you overcome it? I really feel like I'm holding whatever individual there is back from saying everything they want to say.
