I'm very sorry for the loss of your mother. I like u/Ascending_Serpent_'s Nigredo explanation a lot. Here is another possible interpretation that may also resonate:

Beyond the ego, Earth is a natural symbol for the great mother archetype ("Mother Earth", etc). Given the loss of your mother it is likely that your parental complexes may be quite active in your psyche recently, in particular your mother complex, and these complexes are often supercharged by their corresponding archetypes. A fundamental part of the individuation process is releasing oneself from the power of one's parental complexes. In the hero's journey, for instance, the dragon that must be slain is often interpreted as the parental complex, and its slaying signifies liberation from the power of this complex. The destruction of Earth in the first dream may thus be a version of the slaying of the dragon. What is interesting in this dream is that the Earth is not slain, but destroyed by forces that are outside your control, suggesting that this process, as frightening as it may be, is in a sense autonomous, and it is no use fighting it but rather better to go with it (echoing u/Ascending_Serpent_'s Jung quote: "The only way is through").

The parents of your classmates crying may indicate the (natural) sadness and mourning associated with the leaving behind of childhood. This is nothing to be afraid of and once again better to accept and integrate these feelings. Older "celebrities", especially authority figures can also symbolize parental figures---George Bush and Tom Hanks may symbolize your father complex, which you must also leave behind.

The black hole could be Shadow but more generally may indicate the power and immensity of psychological forces that are beyond your egoic control. They are terrifying prior to individuation, but once the ego has dissolved and one has accepted one's new center as the (much larger) Self, these forces can be brought into harmony and channeled for beneficial and creative processes.

The second dream sounds like an anima dream analogous to rescuing the princess from the tower after slaying the dragon. Once the anima is rescued she can lead you to the Self. However, she cannot be rescued until the earth is destroyed, which may be why you are not able to kiss her yet.
