My sister and I call it the 'psychic telephone'

Based on what you've said, I think it's possible that you're not making ppl call you, rather you're empathically picking up their thought forms - ie, they start thinking "I might ring Olive"... then you pick up on that just before they actually ring. In the same way, your DD probably stirs through the layers of sleep for a few minutes before she actually wakes up, again you're getting the incoming information via your intuition. The prediction stuff works the same way.

If you've got a friend who's interested in this, talk about it and see if you can start transmitting & receiving clearer info. I've done this a few times when DH and I have been seperated at the shops - I try to 'tune in' to whereabouts he is, etc. Can be useful LOL!
