Provided that the noun "dream" may mean both images and emotions occurring during sleep and imaginative thoughts indulged in while awake, what adjective would unambiguously modify an event that took place in a night dream?
For example, last night I saw a dream where I was drinking Vodka and playing backgammon with Boris Yeltsin at my kitchen table.
How can this game (or any other event such as encouter, wedding, fight, etc.) be modified in a sigle collocation of an adjective and a noun?
Such adjectives I could think of as dreamful (full of dreams), dreamlike (resembling a dream), dreamed (imagined or hoped for) definitely don't match the idea,
Since in Russian (my native language) there is no adjective for this, and the idea is usually expressed by what may be translated into English as "the game from the dream", I wonder if there's one in English.
In addition, the example sentence might read something like this:
After sending you the message where I had told you about my [the requested adjective] encounter with Boris Yeltsin at the buss stop, next time I saw him in my dream was at a mobile juice-bar—he was sipping tomato juice from a schooner.
