dentist dream

Can anyone make any sense of this dream? It was very vivid and not linked to anything I had been doing in the last few days.

I was at the dentist and the dentist turned out to be my boss, who I actually get on with well. She decided that I was going to need a lot of work done on one of my back teeth - it didn't have to come out but it was going to hurt, probably some root canal work I think. I remember being in the chair hugging myself, with her talking about the treatment, which I would have to come back for later.

It then cut to me running - not away from her, just exercising, but my legs were leaden and although I was running I was actually not moving as quickly as i would have been if walking. I was running alongside fields, but not in them, along pathways and over stiles, seeing occasional people along the way who seemed concerned that I wasn't running fast enough. I was exhausted but kept going. The pathways were always on the edge of woodland on my right and fields beyond a fencce on my left.

I seemed to keep switching between these two scenes, never finishing the run, or getting the treatment at the dentists! Does this mean anything at all, or should I start going to bed earlier!!!!

Any replies would be very welcome x
