>>1067941>Does anyone know anything about this subject?Yup. Intense dreams are caused by intense emotions. You were probably doing something particularly exciting that day, even if that was just a hike, if it were new and exciting to you, that would still qualify.
>>1067946The idea that dreams have 'meaning' is only a half-truth. You likely weren't dreaming about being a lion because you're suppressing wanting to be a furry, but rather the meaning is relative to how you in particular feel about lions.
