Question

Is the word "dream" a countable or uncountable noun?

Answer 1

Countable.

Explanation:

A countable noun is any noun that you can count! Try it: one dream, two dreams, three dreams, four dreams... -- "dream" is a countable noun.

Uncountable nouns can't be described with numbers. For example, we cannot say "one water, two waters, three waters...". Thus, water is an uncountable noun.
