I know what you mean about vivid dreams ! I have them about hatching geckos and snakes.. getting new snakes and flying around by flapping my arms lol.

Last night I had a sucky dream where I was checking on my big girl and she had relaspsed into a full blown RI ...and then I soaked her to get the humidity up... in the toilet

One of my most vivid was me waking up and going out to our kitchen, it seriously looked like my kitchen too including the exact way the sun light fills the room. I went over to the ironing board and started slicing meat off of a human leg that was there to make a sandwich! I mean come on, I am super carnivorous but ... this lol

I've had a lot of the dreams where I feel pain that I wake up with, it's wierd.
That car crash one is really bad
