I get sad when someone dies that i love because its normal for people to grieve that they have lost a loved one.I cry because i know i will never see them in the form of a person again or be able to have a conversation face to face with them or ask them things that i wished i did when they were alive.I do seances alot so if i feel sad about my grandma or whoever i can communicate with them.It actually works for me and i can ask all the questions i ever wanted to know.Sometimes you cannot communicate with people that have passed im not sure why but i can never communicate with my grandfather.I have had a few bad experiences too with doing that.I know that there is life after death (not physical) possibly apparitions.Definatley you can communicate with the dead if your spiritual energy is high enough and theywill tell you where they are
