Hello there.
I want to talk about a dream I had before actually asking the question.
I dreamt that I was in a small room, with only one door. So, I opened the door, which brought me into a very small passage with the very door i just opened, and another door at the end of the passage with an “exit” sign above. I kinda knew that the exit door would wake me up, so I wanted to go back to the room before. But, the door was locked. I was trapped. Suddenly the walls started to move towards each other, making the room smaller and smaller. At the end, I had no choice but to open the exit door, if I didn’t want to be crushed of the two walls.
The exact moment I got out the exit door, my alarm clock was ringing - it was time to get up.
Think of it a bit - In the dream, I chose to open the door THAT exact moment, and it felt like the walls kept pushing me to go through the exit door just in time for the clock to ring.
To me, this is a question about time, and about how there always seem to be a relationship between the dream and the very moment we wake up in reality. For instance, in dreams when we dream someone kills us, we always wake up in the morning, as we would normally (atleast I do).
I had a very similar reoccurring dream when I was young. It was very short and went like this:
The setting was a dark and stormy night and I’m at the foot of the ruins of some temple with stairs that don’t exactly zig-zag, but shift back and forth something like a repeated S if anyone gets that. So I’m basically running up these stairs and I’m passing by pillars and other ruins of sorts and when I get to the top there is an opening into the ruins. The entrance is dark, very dark, and nothing is visible. I hesitate to enter and suddenly a pair of red eyes appears and gazes into mine and then I wake up and it’s morning.
The whole night dreamed up in this short span of some 13 seconds.
Maybe it’s because your subconscious knows that your alarm clock rings at insert time here and “programs” the dream to end at that exact time.
I have had such experience too, but I cannot remember the dream.
