This is nominal data rather than interval or ordinal.  This is because the numbers refer only to non-numerical categories and do not actually have any value of their own.

Interval data is data that has a constant interval between values.  If you looked at how many inches tall each student was, there would be the same interval between those who were 48 inches and 49 inches tall as there would be between those who were 51 and 52 inches tall.  There is no such relationship here.

Ordinal data is in order of rank.  If your data had to do with who had the best grades (1), who had the second best (2) and who had the third best (3), this would be ordinal data.  But these data you have given are not like that.  Dream 1 is not greater than Dream 2, for example.

This is nominal data.  Each number simply stands for a type of dream.
