Tired, tired, sleepy, what are they?

1. I feel very tired and want to sleep when I am awake. I always dream when I fall asleep, and my dreams are messy and complicated, and I can't recall any fragments when I wake up.

2. I was tired, sleepy and hungry the day before going to work, and I was not tired, sleepy and hungry the day after going to work.

3, tired and sleepy, not a day is full of energy to go to work.

4, so sleepy, so sleepy, so sleepy, ah, ah, ah, I have to go to work! Sleepy and tired.

I don't want to sleep every night, because once I wake up, I have to get up early for work the next day, and I am sleepy, cold and tired.
