Why is there a noise coming from the passenger side floor vent in my 99 honda civic?

I just noticed a noise coming from the passenger side floor vent in my car. It sounds like a clicking noise coming from a disrupted fan. the higher my A/C blows, the faster and louder the clicking becomes. I believe this just happened tonight and I have a feeling this may be because my friend kicked something under the passenger side of the dash
