Hi Ana,

That was your grandmothers way of saying "see ya on the other side". You already know what she wanted to tell you. If you were listening you would have heard her say "I Love You, and I'm fine".
Listening is the most difficult skill to master when communicating with spirits. Because they don't speak with their voices and you don't hear with your ears. Those are physical parts. Which a spirit no longer has. You have to listen and look for the signs when communicating. They may not come right away or in the way you would like them to. Unfortently, it requires us to use more than the less than 10% of our brains that we know use. LOL : ))
I'm not use if your grandmother suffered before she passed or not, but if she did you can take solace in the fact that she is now free of the limiting physical body. When ever you need her all you have to do is call.
