I get these all the time, maybe you've been in love before and miss it and your sub conscious is reminding you about that
But yeah i've had dreams where i've felt like i'm in love with the girl and like i've known them for years but when i wake up i never knew them haha and i guess the red discs part is just the wierd randomness part of dreams i've had SAS parachute drop ins in my dreams despite never ever ever being SAS quality.
