Lost

I have a reoccurring dream which always follows the same thread. I have this dream several times every month and each time I have it, it is surreal yet strangely true to life.

It always begins when I'm with my closest friend. Sometimes he is with his wife, but always we are together in some recognisable situation.

Then we leave the house together to go someplace, but he always seems to walk quicker than I am able and always he turns a corner and has vanished out of sight as I reach it.

I walk hastily on searching for him through sometimes amazingly complicated structures but can never find where he went.

It always ends at that point and I always remember it when I awaken.

Any clues as to what it might mean? Or is it just brain jumble.
