Has Sādhna ( Meditation practice) with closed eyes more benefits than with open?

Nowadays, I've been practicing Vipassana (Sometimes anaapan) with open eyes since I instantly start feeling sensations almost everywhere in my body including flesh & organs when I draw my attention there. Actually, I haven't fixed proper time for Sādhna in my routine rather I try to practice it 24hrs by being aware constantly like during eating, walking, listening, sitting (During activity I try to witness activity with detachment) with **equanimity**.

But whenever I give time to meditation with **closed eyes**, I feel my surrounding very dynamic, beautiful & loving once I open my eyes after meditation. So far, I have been taking this as **my hallucinations along with ego** is the reason I haven't cared to give dedicated time for meditation practice with closed eyes.

But now, I want to ask whether I'm missing something? - Should I allot dedicated time for meditation with closed eyes? Are there some benefits? - Is feeling surrounding dynamic & beautiful after meditation a hallucination?
