My Dead Father Appeared In Front Of My Eyes

This is about the first time I actually saw my father as a physical entity and it happened when my sister was dying.We were in a private room as my sister was in the last days of her life and many strange things had already happened over the last few days such as hearing someone talking all around us in the room but the talking seemed to be a long way away and moved around the room and then became louder at times,also my daughter had put a bottle of coke on the top of the clinical waste bin in the roomand it had hurtled off the bin and landed at my feet.After checking the bin to se if it was vibrating or moving we all decided it was impossible for the coke bottle to have done this on its own so we placed the bottle on the bin again,after about an hour the bottle didnt move so I asked out in the room "is that you dad?if it is can you throw the coke bottle again"nothing happene for about 5 minutes and we all carried on talking as normal then the full coke bottle came hurtling towards my feet again and we all knew that my dad was their.Some aunties and cousins came to see my sister as she breathing very heavily and unable to move her eyes though they were open and starting to cloud over,we were all talking about happier times when I saw a mans arm appear wearing a black jacket and white shirt then the hand appeared,I knew immediately it was my father as he had very distinct large hands and a crushed nail on one of his fingers,I stood staring as a leg with dark trousers started to appear.The vision was sat in a chair behind my cousins so I could only see parts of the apparition then it seemed to dissolve in front of my eyes but I knew dad was waiting to take my sister to a better place.
