Two nights at hotel Morgan hose Kalimpong

I stayed in Morgan house kalimpong from 6th April 2022 to 8th April 2022.The campus of hotel was very  beautiful. The main building has office and restaurant. While we stayed in cottage about 100 yards from main building. I came to know about hotel as haunted by my taxi driver at airport.
On both  nights at hotel somebody was knocking on my door around 1am.It was really scary and i had no courage to open the door but knocking was only for 1 minute and then stopped on both nights. I really don't know what was the fact but it was truly scary
