The Importance of Thinking About Dreams

I was having weird weird dreams coming up to like the anniversary of my dad's Birthday, I think may have been his death. My therapist said it is also very possible that our brains are just telling us stories at night or randomly firing synapses About things. So yes he was like it's important to just really think about what how you are responding and based on this dream rather than thinking there some sort of unhealed part of myself because it's like right?
