The word ויחלום, from the same root as ותחלימני והחייני (Isaiah 38,16) “You have restored me to health and revived me,” means to feel strengthened. In King Chiskiyah’s prayer recorded in the Book of Isaiah, it means that the King emerged from his sickness strengthened in his capacity as a servant of the Lord. He had needed strength as he had been on the point of dying. Yaakov, at this point in his life is also in need of חיזוק, strengthening, so that the word ויחלום, means that he became aware of being strengthened seeing he was at the beginning of his career as a servant of the Lord, eventually as a patriarch of the Jewish nation.

Genesis 28:12 והנה מלאכי אלוקים עולים ויורדים בו, “and here angels of G’d were ascending and descending on it.” The vision reflects the fact that man’s actions propel the movement of these “angels,” either heavenwards or earthwards. If man, G’d forbid, instead of serving His Creator, does the opposite, he is also having a negative impact on these angels in the celestial spheres, causing them to descend spiritually. This concept has been spelled out in Pessikta Rabbati 21,8 where we are told that ever since the destruction of the Temple, G’d reduced the number of angels constituting His entourage. However, once Yaakov had become firmly established as a servant of G’d, he was granted an additional vision, i.e. והנה ה' נצב עליו, “and here the Lord Himself was standing above the ladder.” This vision refers to the merkavah of G’d, His chariot.
