Questions & Answers about No creo que la turbulencia haya producido tu mareo.
Why do we need the present perfect subjunctive (haya producido) here instead of the indicative (ha producido)?
The phrase No creo que expresses doubt or denial, which forces the verb in the second clause into the subjunctive mood. We use the present perfect subjunctive because the action of causing the dizziness happened before the present moment of not believing, but the result is still relevant right now.
What would happen to the verb if I dropped the word No and just said Creo que?
If you say Creo que, you are declaring a belief, which requires the indicative mood. The sentence would become Creo que la turbulencia ha producido tu mareo to mean 'I believe the turbulence has caused your dizziness.'
Could I use the imperfect subjunctive (produjera) instead of haya producido?
I know producir usually means 'to produce'. Is it normal to use it for causing a feeling or symptom?
Yes, it is very common. While you can absolutely use causar (haya causado), Spanish speakers frequently use producir to describe bringing about physical reactions, symptoms, or sensations like mareo (dizziness or motion sickness) and dolor (pain).
