its funny now i think puffin, i see some similarities in my dreams from a while ago that kinda refer to your reality checks, 1) the nose plug, it wasnt holding my nose, but in my dream i was able to swim underwater for as long as i want and i could breath. 2) the lights, i remember in these dreams i have been scared like their is a ghost in my room or something, and every time i try and turn a light on they are really dim and wont go any brighter, and also in those dreams i try and open the door and its like something is trying to push it closed so i cant get out. i have had both of these dreams a few times, but never got to a reality check scenario in the dream to help me become lucid.
