Does Vipassana arise from Samatha/Anapanasati meditation? or is it another trap of monkey mind?

I'm novice to meditation and Buddhism. Apologies if this is silly question I've been practicing antipasti meditation for few months. While I watch/understand my breath, when a thought arise I use 6 Rs and let it go and come back to breath. However when meditation gets bit deep while the mind is somewhat still, I come to a deep realization. It's like everything's zoomed in. - Is this an early levels of Vipassana? Then I get confused that this is a call from my monkey mind so I go back to 6Rs. Is my practice correct? Bit confused over my approach. Also I don't have a meditation teacher. Appreciate your feedback :)
