Affirm that I use Freud's point of view, dreams are the embodiment of my inner wishes.
That baby should symbolize someone or something you hate. You have the idea of making this person or this thing disappear, which is definitely impossible in reality, otherwise you are a murderer. So reflected in the dream, because of some factors (this place is very complicated, so I won't explain it), your thoughts can't be directly presented, so you become a ghost baby who wants to hurt you, so you can kill him in your dream, but you must be afraid of killing people, so your black things are diluted, and the baby disappears directly instead of falling in a pool of blood, so you won't be so upset. And this is a love love, just a dream, suggesting that it is impossible in reality. When you wake up, you see two classmates. Maybe it has something to do with them.
You suddenly disappeared, on your way to a new school, maybe because you really want to go to a new school? Still like this school relatively? Another possibility is that two schools represent two people or two things, and you prefer that "new school". In the dream, you are still wondering whether to pass on autumn clothes or winter clothes, with autumn as the background and autumn to wear. Why are you hesitating? I'm afraid this represents two different people or things. You feel a little difficult to decide. You think "autumn clothes" are more suitable, but you can't put down "winter clothes". I think what's bothering you recently?
