Did your dad called anymore? I once experienced two times in the middle of the night but I did not dare to pick the phone, funny when it rang, I immediately thought of him. My mum told me that she once picked the phone at about 3am and there was a man who said ‘hello, hellp’, she asked if it was my dad, he did not answer. One or two nights later, my home phone rang in the middle of the night.
Your incident left me a very deep impression and I thought of my dad when I first read your story. He left the world too sudden and we had plenty of things we wanted to say to him. He passed away in 2008.
