The words I’ve read

I like to go to sleep,I feel so hot
I need an ice cold drink by my old bed
There must be something else,but I forget
Why was Albert Einstein  full of smut?
Relatively speaking, he was shot
A photon waved and particled a dot
When you’re living you’re not really dead
I like to go to bed,I  have no plot
I buy a  book and eat the words I’ve read
