Dream Help : What does this mean?

Tweet

I guess before I tell you what my dream was, I should give you some background. Three of the people who were in this dream, I often refer to as "old friends", now I know most people might think these are just friends I lost touch with. No, we kind of ended our friendship a little rough, but nothing I regret too much. In any case, Here is the dream : My husband, his mother and I were at a grocery store, I'm thinking it was a Harris Teeter. We never go to Harris Teeter, in fact I think the last time we were at a Harris Teeter was when we went to spend the night with his mom at her bosses house who wanted her to house sit. In any case, in the dream we were at Harris Teeter. I think we had looked for something, but that part either wasn't in my dream, or wasn't something I remember. In any case, we were leaving the store when I saw three of my "old friends" (remember explanation of "old friends" above)they were in line from the friend I was the closest with, to the friend I'd known the longest, to the one that I didn't really talk to. The one I didn't really talk to was either in a hospital bed, or a wheelchair. Her leg was either up in the air in a cast like they do, or was just laying on the bed, or in the sitting position in the wheel chair. My hair was up in a bun, and so I touched the bun with my left hand, the hand that has the ring on it. the friend that was in the middle, the one who I said I'd known the longest, got out of line and ran over to me, and said she wanted to take pictures of the ring. I was hesitant at first, I looked at my husband and he gave me the "go ahead" look and nod. So she took pictures, and we started talking like old friends. That was pretty much when the dream ended. We had looked at their profiles yesterday, and then I dreamt this last night. My husband also told me this morning that he saw who he thought was another one of my old friends, who wasn't in this dream. I told him to start a discussion about that, but I don't know that he will or not. So what do you think of this dream? Is there anything you can tell me, like maybe why you feel I had this dream? If you need more information, don't hesitate to ask.
