Can the living send text messages to the dead?

LZ, I don't know if you are joking, I hope not, because I have experienced it. I remember a few years ago, one of my good classmates unfortunately fell from the upstairs and died. Later, about 1 month passed, and one night I received a very strange short message, that is, the content sent to me by my unfortunate friend was probably (I can't remember clearly after a long time): I am your good friend XX, how are you doing now? And that number is weird (I forgot specifically). I dare say that I have never seen such figures. Even weirder, the message disappeared the next day, and I never deleted it. If I had made up this answer, I would have been killed by a car and killed by thunder when I went out. Please don't doubt.
