I am a boarder in a secondary vocational school. I go home once every half a month. Our dormitory has four double beds and eight beds, with windows facing south and north.

Your dormitory is a normal dormitory, which is not easy to be messy.

Let's analyze:

First of all, at present, you are the only one who has problems, and there are no other students, so the overall probability of problems is relatively small. But I still have to ask you, is there a corner of the building or other sharp things facing the window outside the window? Is your dormitory at the end of the corridor or is the door facing the stairs or bathroom?

Secondly, you are the latest problem. So has there been any change in your living environment recently? Were there any strange things or reasons before the problem appeared? Did you put sundries under the bed? How do you usually sleep?

Finally, there are many feng shui problems, and there are always fewer things lost. Among the things you lost, your glasses and ID card are definitely not to be stolen, so you can temporarily rule out frequent theft. I suggest you think more about whether you have done anything bad or said something you shouldn't have said before the problem appears. This comparison affects your luck.
