A common construction in English is:
There is a person in the room next to me.
However, this is ambiguous because it’s unclear whether the person is in a separate room that happens to be adjacent to my own, or whether they are in the same room as me (and standing beside me).
Given this is grammatically correct, how would I best go about specifying which is the case?
There is a person in the adjacent room to mine.
There is another person in the same room as me.
Both seem unnecessarily confusing.
