May we talk to our beloved departed ones?

Yes StellaMaris , I've seen that happen several times as a nurse and I experienced it myself with my Mom. She had end stage CHF and was on Hospice in my home. She had a fairly normal day was aware and alert even after eating a good supper. But later that evening following a phone call from my brother she took a sudden turn for the worse. She continued  to struggle to breathe and wasn't responding to the Lasix  that I administered per her Drs. advice. Her oxygen wasn't helping her either and her anxiety made her struggle more. The Hospice nurse was on the way as was the Dr who said to give her some of Ativan drops which did help. My daughter was sitting on her left holding her hand and I was on her right stroking her arm telling her to be at peace. We were praying the Divine Mercy Chaplet repeatedly when I could sense she was going by the change in her breathing pattern. Neither the Hospice nurse, her Dr nor the priest made it before her last breath. I think she went quickly because we were with her telling her it was okay to leave and for her to be at peace. Her greatest fear was dying all alone like my father did in a hospital in the middle of the night. My sister had been praying that she go quickly and peacefully and I was praying that she be accompanied to heaven by the  Angels. She died on September 29th in a matter of a couple of hours so I feel that both of our prayers were answered. One of my Grief Share sessions provided the following quote as a condolence to those of us on our grief journey. This grief program is Christ based one but not a Catholic Church one but I think the sentiment expressed fits into Catholic teaching.
