Trapped in a slow motion race?

It's something like I am in a race, initially quite ahead of everyone and then I see one by one my friends crossing me and taking over, moving so fast that I loose their sight and no matter how hard I try I cannot keep pace with them, meanwhile more people join in and they too move way past ahead of me. It's like those dreams wherein you are trying to catch someone or trying to scream but you can't, you try very hard but all in vein. I guess you know what I am talking about.
