Dream interpretation

Last night I dreamed my car got stolen. I have actually had this dream before but usually I have it when I go home to visit my Mom. How this dream usually goes is that I look out the window and see people stealing my car. I try to yell at them to stop but no words come out of my mouth so they steal my car.
Today I thought that maybe there was some deeper meaning to this dream so I Google "dreams, stolen car"
This is where I learn that stolen car dreams can mean loss of identity, loss of job or failure in relationships. This makes me think about why I would have this dream.
Earlier this summer I pulled a muscle in my shoulder during a workout. I recently started sewing part time at my old job for a few weeks but the shoulder is rebelling. This makes me feel weak and wimpy as I try to figure out how I'm going to work around it and if I'm just going to have to quit the second job.
Also I'm fairly strong and into fitness and I think I define myself by my strength. I sometimes don't think I would have the confidence to handle the rejection that comes with writing if it wasn't for running, biking, swimming and kettlebells. The good news is that I have been running more as a result of my shoulder hurting.
Maybe I am feeling a little loss of identity as I deal with my new wimpy self and my inability to sew right now. I can still do my normal job but with the economy being so slow I have been trying to find ways to make more money.
I know that if I am going to write that I can't work two jobs and that my stitching job will probably be the one that falls by the wayside. I have known that for a while and have tried to quit the stitching job for two years but I keep getting sucked back in. So even though I guess I'm having anxiety dreams about my changing identity I should just embrace it.
