I was reaching behind my lamp and it fell over, hitting me in the head and shattering. What I'm wondering is if it is safe to go to sleep. This happened just under an hour ago and the only symptoms I am currently experiencing are dizziness and pressure in my head. I have to get up at six AM tomorrow morning and am working until 9:30. I really need my rest but I'm terrified that something might happen to me if i try to sleep. Help?
