This is asking if subjective meaning is objectively meaningful which, by definition, it isn't. Subjective meaning is choosing to find meaning in things even though they don't matter in the grand scheme of things.

I'm guess I'd be happy until I found out I shouldn't be in that situation. But what's an illusion, and when can we stop pulling back curtains? We are solid matter, but there's mostly empty space in our atoms. So we think and feel like we are solid, but we are nothing more than fluctuations in a quantum field as far as we can tell. Shall my subjective happiness be dashed on the off chance I'm actually just a passing fluctuation in the echo of the big bang instead of a human in the only reality there is?
