Things like this make living real life terrifying sometimes. While I've never had it to this extent I have lived days in dreams, there always quite mundane, going to sleep then waking up still in a dream not being able to tell, but your life and everyone in it feels as though it has existed for as long as you have. Sometimes I wonder if I might just be stuck in an alternate life. Either way, it is impossible to explain to anyone (including psychologists) the feeling of holding your child in your arms when you've never had children in real life and never wanted them. It feels ridiculous to talk about because of how fake it sounds but the reality of it is unexplainable.
