be and feel

[Mrxkms]

be and feel
be sleepy / asleep
feel hungry / full / sleepy
What I want to ask you about is that a restrictive use of these adjectives with the verbs be and feel
I read this information in a book teaching English and it was categorized as I mentioned above
Is it wrong to say for example I feel sleepy or I am hungry instead of I am sleepy and I feel hungry ?
In other words is it wrong to mix between be and feel before these adjectives?

No, you can mix them as you have done.
