dream interpretation, plant grow off body?

I had a really weird dream last night...and was wondering if anyone has any ideas on what it could mean. basically, I looked down at my legs. around each leg, there was a plant growing around my ankle. Like a bunch of little plants. It looked similar to the picture I post below. but the plants were smaller. they grew around my ankle and around the part right before my knee cap. I was really creeped out by it. I thoguht I needed to see a doctor. Instead, I pulled the plants out of my right kneecap. And realized I had to push the roots out from under my skin too. I did this, and it didn't grow back. I came to the realization in my dream that this is because I didn't clean myself properly after cleaning a dirty room. The chemicals or germs made the plant grow. Any ideas what it could mean? It really felt strange and more of a negative feeling than a positive.
