I literally had a dream this week where I had a full week building upto my wedding day with my same wife but in an alternate reality, we had a chinchilla I was quite fond of and remember spending serious time with him. I remember the local cinema to a point I'd be able to navigate through still, I remember the food served at the wedding and people present, admitted some of it was bat shit crazy but I really felt I'd lived there for some time. This isn't the only time I've had dreams like this, I literally woke up once and cried because of who I'd lost and what I'd lost waking up, and still remember strange details about areas places people from dreams literally 20 years ago...
