I guess the more obscure ones when they happen are meant to be a reassurance that I am on the right path.
What Chambers says here is true of every vision given to man that we read of in the Bible; there is a Purpose for specific fulfillment in it, Perfect Reason why it is sent by God.
Jacob received a vision at Beth-el ("House of God"), but he did not interpret the vision rightly:
Jacob left Beersheba and set out for Haran. When 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. He 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. There above it stood the LORD, and he said: "I am the LORD, the God of your father Abraham and the God of Isaac. I will give you and your descendants the land on which you are lying. Your descendants will be like the dust of the earth, and you will spread out to the west and to the east, to the north and to the south. All peoples on earth will be blessed through you and your offspring. I am with you and will watch over you wherever you go, and I will bring you back to this land. I will not leave you until I have done what I have promised you."Because the interpretation of the vision was not an accurate one, idolatry was practiced at this place, at Bethel.When Jacob awoke from his sleep, he thought, "Surely the LORD is in this place, and I was not aware of it." He was afraid and said, "How awesome is this place! This is none other than the house of God; this is the gate of heaven."
Early the next morning Jacob took the stone he had placed under his head and set it up as a pillar and poured oil on top of it. He called that place Bethel, though the city used to be called Luz.
Then Jacob made a vow, saying, "If God will be with me and will watch over me on this journey I am taking and will give me food to eat and clothes to wear so that I return safely to my father's house, then the LORD will be my God and this stone that I have set up as a pillar will be God's house, and of all that you give me I will give you a tenth."
~Genesis 28:10-22
When Jesus came He spoke of Jacob's vision and made plain what God meant in sending it to our patriarch; He declared its fulfillment in Himself:
He then added, "I tell you the truth,Jesus is the only Way - "stairway" - to heaven, to the House of God! No other "ladder" will reach, because no other Way began Above and came to earth as Jesus Himself did, amen, what Glory! All man's idolatrous attempts to ascend to God are ladders that fall far short of the goal at the top, but Jacob didn't know that yet.
you shall see heaven open,
and the angels of God ascending and descending
on the Son of Man."
~John 1:51
