Having To Climb Through A Small Space

In my dream I was following this lady and she was showing me the way out.  We went through this door and down these steps.  Once we got down the steps there was this small opening at the bottom of the door that I had to climb through. I didn't think I could make it through the small opening of the door and the lady had already went through the opening.  I pushed on the door to see if it would open where there was a  small opening, but the door was locked and wouldn't bulge.  So, I walked back up the stairs to go back the way we came, but the door wouldn't open.  So, the only way out was the small opening.  So, I went back down stairs to go through the opening, but I woke up before I could see if I made it through the opening.  Any thoughts
