That's happened to me quite a lot, and I'm never surprised when it does - something inside me seems to know the difference between simply thinking of a friend, and thinking of a friend who's about to show up. I'm sure if I could reproduce the feeling I get, they'd *all* show up whenever I thought of them. Maybe it's the same feeling that manifests cups of coffee and pizzas for other people, maybe it's the feeling combined with the certainty that they'll appear that manifests them. Maybe not - I may have 'believed and received', but I don't remember taking any action or even asking them to show in the first place
Maybe I've just had too much beer...
The 'telepathy' comment reminded me of when my sons were around three and four (they're seventeen and eighteen now), and we went through a phase where I'd be thinking of something and I'd get a verbal reply to my thought from one of them on the subject, even though I'd not actually said anything. Sometimes we had brief but entire conversations in this way. Weirdly, I think I imagined that all mums communicated with their kids like this and it just seemed normal to me at the time. It's only now that I look back that I see it as pretty amazing. I've since had two daughters as well, and this didn't happen with either of them.
