A crazy dream brought on by consumption of NyQuil, or other similar cold/flu medication.

Similar to a Fever Dream.
"That double dose of NyQuil gave me the craziest NyQmare last night. Dig... Clay Aiken and I were sitting on Carmen Miranda's shoulders eating bananas from her headdress thing while she was being tickled by Eric Massa, all while Liberace and Elton John played dueling pianos."
