Mark 4:38

And he was in the hinder part of the ship
That is, Christ was in the stern of the ship: the Persic version renders it, "he was in the bottom of the ship, in a corner", but very wrongly; here he was

asleep on a pillow,
which some say was a wooden one, framed at the stern: however, he was fast asleep on it, being greatly fatigued with the work of the day; (See Gill on Matthew 8:24).

And they awake him, and say unto him, Master, carest thou not that
we perish?
The disciples came to him and jogged him, and awoke him out of sleep; saying, Master, arise, and save us, or we are lost: hast thou no concern for us? how canst thou lie sleeping here, when we are in such danger? are our lives of no account with thee? is it a matter of no moment with thee, whether we are saved or lost? They seem to say this, not so much praying and interrogating, as complaining and reproving.
