Come in and tell me the strangest real experience you have ever had?

I feel that I have really experienced a few strange things, but I can't tell whether this is a reality or a dream, because every time I dream, my subconscious seems to know that it is a dream, because sometimes I am scared in nightmares, but then I subconsciously remind myself that this is just a dream, but I did experience a strange thing in reality, that is, when I was in primary school, I obviously finished my homework on weekends, and then I went to school on Monday morning without my homework. I remember very clearly that I came home in a hurry and found that all my homework was there except my math exercise book, but time was tight and I had to get back to school before the flag was raised, so I gave up decisively. I went home at noon and rummaged through it many times, but I clearly remember lying in bed and not taking it out. Then my mother came back, and he helped me find it. We turned the house upside down, but there was no trace of my math exercise book. Usually he doesn't appear when he is in a hurry to find something, but he will appear in front of you when he is irrelevant, but my exercise book hasn't appeared for a long time. I didn't see it until we moved and it was empty for half a year. I really feel very strange. After all, how can a real thing disappear for no reason?

Another thing is that one morning, the room was not bright at dawn. When I opened my eyes, I saw a shadow with long hair standing in front of the bed, which scared me. I thought it was because I was dazzled, but I saw shadows many times. I told others that nobody believed me, and I began to doubt myself, but I really saw it. It's terrible to think about it now.
