Land of Crossroads and Memories

This is a bit of a late entry, albeit my first dream journal entry, but nevertheless I remember some of my dream. I mainly remember traversing around the upstairs portion of a mix between my high school and college, it's main feature being a wide set of stairs that goes down to the first floor. I suddenly felt dizzy near the staircase and fell on my knees, just a few inches away from the stairs. I looked up and saw one of my previous teachers -- my Digital Electronics teacher -- and said hi to him. I had the knowledge of myself graduating, so my teacher looked a bit surprised to see me. He was wearing a red long-sleeved shirt and had khaki pants accompanied with black shoes; I then went forward and proceeded down the stairs, tumbling to the bottom...

... I then questioned the fact of not feeling any pain. At the bottom, I realized I was dreaming, but I hadn't reacted quick enough to my fading scenery. Upon waking up, I had done no attempt at a DEILD or a WILD, for the thought of doing so didn't cross my mind. In order to have stayed in my dream, I could've rubbed my hands together, or I could've stayed perfectly still when I awoke, in order to possibly enter the dream again. I didn't, though, but I must be wary of the options in the future.
