Full of dreaming; characterized by active dreaming or imaginative activity.
From dream + -ing (present participle/gerund suffix) + -ful (meaning 'full of'). Combines a gerund with -ful to describe something filled with the act of dreaming.
This formation (gerund + -ful) exists in English but sounds awkward—'full of dreaming' would be more natural than 'dreamingful,' showing how -ful works better with simple nouns than with gerund forms.
