zzz - dream

I have this series of 3 dreams in a row almost every night involving a giant black snake roaring in my face with enough power it starts to shake whatever building im in and it starts eating people around me, i manage to get out and think i wake up. next i "go back to sleep" and "wake up" to my mother being in my room, leaning over me extremely angry but the entire room looks like there is a black light on and her eyes are glowing green, then im in the desert walking over dunes endlessly. Usually at the end i actually realize im dreaming and i start suffering from sleep paralysis. At this point i wake up in the real world panicked and i can remember the dreams for hours afterwards. I cant tell if its real, but i do remember waking up between each of these dreams. Every night for 3 nights.
