Beautifully put, free soul.
I have experienced a connection with someone who was dead, I don't want to go into details here, but I do believe in life after death. It was unexpected and I am not crazy. I think sometimes the dead linger for a while, especially if they are concerned about something and can't let go.
I don't think we need to dwell on it much, just try to give more than you take in this life. Ease suffering if possible.
