DNS question, canonical name

Why is the canonical name/CNAME jay.com I think that is the "A" record.
www.jay.com points to it, not the other way around.  
Could someone help me wrap my head around this?
If there was no CNAME, then we would just have jay.com

-> ns www.jay.com
Non-authoritative answer:
www.jay.com    canonical name = jay.com.
Name:    jay.com
Address: 54.183.231.34


-> ns jay.com
Non-authoritative answer:
Name:    jay.com
Address: 54.183.231.34

-------

!(Again, below we have that "jay.com" is the cname. (as if it is pointing to www.jay.com, but I think it's the other way around...

-> dig www.jay.com cname
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.2 <<>> www.jay.com cname
