Is it normal to be in a dream-like state for a day or so?
So I've had these strange events 3 times so far but one time was so severe that I felt like sharing it here to hear your opinion:
It was a week before the exams and I was just going to school like a normal day, I felt a little more dream-ish than normal, wasn't really talkative and everything kind of got on my nerves, but i tought I was just having a bad day. That was until lunch started and things started to get more severe, it felt as if I was starting to lose contact with reality and I was making up every person I came across, it only gets more creepy from here on, me and my friend were walking to a bench and I started to mumple something about a squat and then I suddenly began crying without any reason (he didn't see that I was crying). 5 minutes later when we were heading back to school I started laughing excessively... but then the creepiest part of all started, another friend of mine was 4 meters away from me and apparently I was looking right into his eyes but I didn't see him. So when I came to school he was angry because he I "ignored" him.
The next day things were getting better but it still wasn't the same, instead of having extreme emotions from minute to minute I was feeling nothing at all.
There are still alot of strange things that happend that day but I don't feel like writing them all down haha.
So what do you think? Is it normal or not?
