That is because when you used $d you were actually assigning NULL to your array: myarray for 3 consecutive times.

This is the reason why it was printing NULL followed by number of occurrence: 3.
Code:
$ awk 'BEGIN{while("ls"|getline d) {myarray[$d]++}}; END{close("ls");for (i in myarray){print length(i), myarray[i]}}' /dev/null
0 3
