Narrative:

I was flying at 2;500 feet inbound to kads; and the tower advised 'proceed direct to the numbers'. In my experience at kads; this always means to descend directly towards the approach end of the runway (the numbers); and it even suggests a request to proceed without delay (direct to the numbers; not a more typical base-final approach). Kads is often busy so the tower often provides such routes to expedite traffic handling.as I was descending; the tower contacted me and asked my altitude when I was at about 2;000 feet. He was clearly not pleased that I was descending; but advised ok to proceed. He said he had advised me to stay at 2;500 feet; but I am quite certain he just said 'proceed direct numbers'. In retrospect; I can see now that he could have meant proceed laterally to the numbers but stay at altitude. But since I had never been asked to do this; I did not even think of that as a possibility. What I should have done is confirm my altitude intentions. For my lesson learned; it is to always confirm altitude intentions; even if it seems otherwise clear to me.
