Weird door

I have been looking for my DG in my past few lucids but there was always something stopping me. Everytime I call for my DG a weird black door appears. Unfortunatly each time I try to open it, I get distracted and the door disappears or the door is locked. In one lucid, I had a key so I tried to open the door but the key broke and the door disappeared. What does this mean? Has this ever happened to anyone before?:?

The only thing I can think of is that maybe your Dream Guide thinks that maybe now isn't the right time.

Maybe it wants you to grow more, mature more. (Not saying that your immature.)

Have you tried passing through the door? Perhaps your dream guide is giving you an exercise in dream control.

I also agree with Vegan's interpretation.
