Jacob's Ladder refers to a ladder from Earth to Heaven as described in the Bible (Genesis).
The ladder signifies the "bridge" between Heaven and Earth, as prayers and sacrifices offered in the Holy Temple soldered a connection between God and the Jewish people... but not all ladders point skywards do they?
Bear in mind the term "heaven" originally referred to the sky or the area above the earth where the "heavenly bodies" are placed. As Christians we are taught God and his angels are the heavenly host... they obviously live in the skies above then...
So here's a question for you:
If the ladder doesn't point skywards, is it still possible to make a connection between Earth and Heaven?
Personally I'd answer "Yes" but then I'm just a heathen soul who doesn't believe in the Kingdom of Heaven, God above, etc. I do believe if you have faith it doesn't matter where you stop to pray... or how you go about it... no facing east, bowing of heads, or looking skywards for me!

I'd say you were getting in too deep, except that the subject is too high for that.
