I am sorry you lost your daughter.  I can't imagine your grief right now.  So your son's experiences are of your daughter visiting him?  What kind of experiences?  I understand your jealous feelings.  If I were you I'd be thankful, though, that your son is having visits from her because she's probably trying the best she can to just get through and maybe so far this has been the easiest way.  They say that we can block these things out of our perception due to our grief.  I imagine that in time you'll also be able to receive her communication with you, because it is my belief that she's actually communicating with you already but you're not yet able to perceive it. 

Try to remember your dreams too because that's another easy way for our loved ones to visit us. 

Have you read any of Bruce's books?  Take a look at the articles he shares on this site.  You can find them on the navigation menu bar at the top of the page.  He outlines how you can imagine communicating with someone deceased and shows you how easy it is to actually ease over into real contact. 

I hope you find comfort here.  There are a lot of great people here who can help you in their own ways, either just giving comfort or sharing their own experiences and beliefs. 

Love,
Vicky

Sorry to read about your pain.  I second Vicky's recommendations about Bruce's work and info.
