Alright, I’m gonna go to bed. Sleep well. See you in the morning.
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means lie down so the verb vocab version is to lie down, but what you're really doing is trying to sleep.
The reading is the same as the reading you learned with the kanji. So, you can go ahead and lie down for a moment before moving on to the next item.
