Why would angels climb a stairway if they have wings?

I was just reading about [Jacob's Dream at Bethel](https://www.biblegateway.com/passage/?search=Genesis+28%3A10-22&version=NIV) and I had a question: *Why would angels be ascending and descending a stairway (or a ladder, in other versions of the Christian Bible) from Earth to Heaven if they possess of wings?* ># Jacob's Dream at Bethel > >*10Jacob left Beersheba and set out for Harran. 11When he reached a certain place, he stopped for the night because the sun had set. Taking one of the stones there, he put it under his head and lay down to sleep. 13He had a dream in which he saw a stairway resting on the earth, with its top reaching to heaven, and the angels of God were ascending and descending on it.* > >Genesis 28:10-13 | New International Version (NIV) There seems to be no denying that in the Christian Bible, [angels have wings](https://christianity.stackexchange.com/questions/4986/where-did-angels-get-their-wings) .
