Dreaming with Accusative Subjects
In Icelandic, verbs describing experiences that happen subconsciously or outside of your direct control often take a "quirky subject." Instead of the standard nominative case, the subject of these verbs is in the accusative case.
The verb dreyma (to dream) is one of these verbs. To say "I dream," you use the accusative pronoun mig instead of ég.
If you state what you dreamt about as a direct object, that object is also in the accusative case. Both the dreamer and the dream itself take the accusative. The past tense of dreyma is dreymdi.
Suspicions
Like dreams, suspicions often occur to us as involuntary feelings. The verb gruna (to suspect) also requires an accusative subject.
If you suspect someone of doing something, use the preposition um followed by an infinitive phrase (starting with að).
If you simply suspect someone or something without adding an action, you just use an accusative object directly.
Describing Dreams and Suspicions
When recounting strange experiences or sudden suspicions, you will often use descriptive adjectives. Remember that adjectives must decline to match the case of the noun they modify, which will often be accusative when used with these verbs.
You can also combine gruna with um followed by a noun to say you suspect someone of a specific incident.
