So, picture you're having a dream, a normal one (...if dreams were actually normal), you're just going around and then you're not yourself anymore, someone came to front and took over without even noticing. Well, this happened to us.
The events that happen in our dreams tend to reference on whatever happened in our life, so me starting to dream about texting my boyfriend and the enviroment changing to known places was something that I did, before Berry took over because of a front triggers of theirs happened.
We asked after waking up to another system "Hey, have this happened to you?" and they said "yes, it has, a couple of times", so we ran that conclution that we have not gone insane, it would've been worse if they said "No" considering the fact that I fell asleep fronting and then Berry woke up fronting next morning.
So that was something.
It is weird.
The real question here though, is that if this is one of the reasons why our sleeping pattern changed so drastically ever since. But, only a person can assume, the real answer is something that only the universe might have.
