This was my father's experience. I have no personal experience in paranormal sightings and am more of a skeptic (hence the username). But, even though I have studied science and work in Information Technology, and somehow come up with explanations for most things, I kind of want to believe in the existence of souls. This is kind of personal. I lost both of my parents some 4 years back, in a span of 6 months. A part of me wants to believe that they still exist somewhere and are capable of watching me. I would love to get a sign from them.
Now the story. So my father had a few stories to tell. Earlier I was never that much interested in the stories, though I found them intriguing. This happened when he was in his 40s I guess.
So he was an auditor and would usually be rather busy with his projects. At one time, one of his elder colleagues got hospitalized and my dad was not finding time to visit him. Finally he made it to the hospital one day, but was late and the visiting hours were over. He inquired at the reception if he could still visit and they declined. Now he was really keen on visiting since he might not find time the next day. So in his desperation he asked a passer by for the directions and started climbing up the stairs. The people at the reception were still asking him not to go up to the room. But dad said, he will simply wave from outside and will come back immediately. While saying this he raced up the stairs.
He reached the room, the curtain was not pulled. He saw his colleague and waved at him. His colleague smiled and waved back. After this dad turned and climbed down the stairs.
When he reached the reception, the people there seemed obviously unhappy. They were expressing discontent saying they were trying to warn him. They said that they were trying to stop him because he won't find anybody in that room. The man my dad wanted to meet had passed away that afternoon.
My father believed that this was his colleague's final goodbye to him. He was really close to this colleague and spent a lot of time together.
My logical brain never found an explanation for this, other than hallucination. But the situation was normal and his health was perfectly fine. Would love to hear feedback on this one.
