It’s a nightmare for me. It’s simply a 2D world in which an invisible thing jumps over flowers. That goes on for an eternity and then suddenly a 2D volcano appears and is essentially cut in half since you can see a boulder with a kind of face on it. One second it erupts and I wake up in sweats.
Based on the content of the dream, the jumping over flowers in a 2D world could be symbolic of feeling trapped or limited in some way. The appearance of a volcano that is cut in half could suggest a sense of instability or a situation that is about to erupt. The boulder with a face on it, in this case, may represent some kind of obstacle or challenge that the dreamer is facing.
The sudden eruption of the volcano could signify a release of tension or pent-up emotions. As opposed to a "nightmare," it might be helpful to see this dream as an opportunity to reflect on any ongoing issues or conflicts that the dreamer is experiencing in their waking life and the need to find a way to address them.
