Dunhuang Hotel Horror

I arrived in Dunhuang yesterday afternoon, which was my sixth time there. It was always good and nothing strange happened, but strange things started when I checked into the hotel yesterday. The hotel is located near the Dunhuang Museum and I have passed by before. Yesterday was my first time checking in, and I don't know if it was because of Gao Deding. The front desk gave me a last room. As I walked towards the end of the corridor, I felt more and more hesitant, hoping it wasn't the last room. But in the end, my heart sank. At that time, I didn't really want to stay. My boyfriend said he had nothing to do, so he opened the door and knocked on it three times before we went in. I thought we could make ends meet for the night anyway
As soon as I entered the room, I felt extremely cold, which made me feel uneasy. My boyfriend is usually very afraid of heat and finds it very cold. So we went to put down our luggage and eat, and saw Dunhuang again
After returning to the hotel, I turned on the air conditioning and set it to 29 degrees. After washing up, I was ready to go to bed, but I inexplicably felt nervous and uneasy. The air conditioning at 29 degrees also didn't feel hot at all. If my hands and feet were exposed, they would feel cold. This has never happened before. Even after 2 o'clock, I still couldn't fall asleep. Although I took sleeping pills, I had a strong sense of instability. So I turned on the toilet light and chatted with my boyfriend all the time
Not long after turning on the light and lying down, something that scared me happened. We were chatting and a white light flashed from the ceiling panel light strip above our heads! Immediately after, the opposite light strip flashed with white light, and we both saw it vividly. There was no light source that could create such an effect, it was truly stunning!!
This is not over yet!! My boyfriend's phone lit up immediately! No notifications, no messages, nothing! And it was on the bed that we thought was 1 meter away from (because I was afraid we would put the twin beds together). When my boyfriend saw it, he pressed it off and it lit up again within a few seconds!
Since my boyfriend was really tired after 3 o'clock, I couldn't fall asleep no matter how hard I tried. I was constantly anxious and couldn't hold on until after 4 o'clock, so I woke him up and changed to a nearby hotel, where he fell asleep in seconds
I still have lingering fears today after encountering this situation for the first time
