Hmmm... I usually fall asleep super easy, so my list is what wakes me up in the middle of the night and keeps me awake!
5. When a song on my playlist comes up that I'm apparently supposed to hear (I sleep with music playing each night)
4. Too hot or too cold, depending on the season
3. Super thirsty because I ate cheese before bed
2. When the Holy Spirit wants to bombard me with Scripture (okay, okay, God! I'm up now... Wait, what? Leviticus again? Oh brother...)
1. God decides He wants to chat... Usually over coffee coincidentally
