I posted a question about this somewhere else but nobody really understood what I meant, this will be the first proper post I'm making I think. Just something keeps happening, I'm not sure what, it's like becoming 'not here' , I was wondering if anybody could help me find out what it is? Thank you to anybody that might

This is going to be difficult to explain without sounding silly. I spend a lot of my time thinking wherever I am, and sometimes I think too hard or too fast, which can be scary. Sometimes people say I'm distant, like when they wave a hand in front of you to see if you're focused, and then you snap out of it. I guess that's day dreaming. Something similar has been happening but I don't know what, I posted another question the other day and somebody messaged me talking about schizophrenia because of all of the things I said, and they sent a link with this big list. The list made a lot of sense and essentially everything on it was something I could relate to. By no means though do I think I have schizophrenia, or at least anything diagnosed... Anyway I've been daydreaming, I'm not sure if it relates, but it's not daydreaming. I won't realise I'm doing it. It's like suddenly slipping into another world, and everything in front of me and all of the sounds around me just disappear and it's like being put into a dream world, but while being awake, and I don't realise it's happening, and I will be exploring the second world. Sometimes it's a realistic place and other times it's like a fantasy, and I will maybe talk to somebody in the world, and after a while I just 'snap out of it'..

Then I realise that everything in the other world was not real, and it's like being suddenly out back into reality, and I will realise that I haven't been exploring another reality, but I have just been sitting there sitting into space like a statue.. It's scary because sometimes people try to 'wake' me but can't apparently, and I just sit there, please can somebody explain to me what it is? I know it's not daydreaming or even dreaming at all, is so real, I'm really sorry this probably all doesn't make sense
