My dad passed away 17 years ago. After he had passed away, in the first 2 years, he came back to visit us quite often, almost every night. On his "first seventh" my mum bought durian for him for praying, knowing he loves durians. The next day, i.e. the eighth day, me and my mum saw finger prints on the durian, it's not left by me or any other family members coz when we open the durian fruits, we pour the durian fresh on the plate without touching it. My dad had habbits like opening the gate louding, banging the lock against the wooden door and waking louding around the house a few rounds in the morning around 5am. Theses were heard at nights and morning after he is gone. My mum felt my dad seating next to her on the bed while sleeping (she's a light sleeper), coz the mattress sank down. I heard him walking around the house into my room around 5am, but see nothing. These movements gradually ceased over the years, but some nights and morning, me and my mum can still feel or hear him coming back, walking in the house. There's nothing to be scare of as long as your conscience is right.
