blue clouds after eyes roll back

hello, hope everyone is well. I’m one month into meditation and i’ve encountered some interesting phenomena recently. i’d see different colours in the form of “clouds” appear. It’s always blue, but i saw purple and yellow once. lately, my eyes would naturally roll up as i meditate, and when that happens - a strong, big wave of blue clouds would appear. I’m in awe when that happens. of course, the goal of meditation is to not chase or be attached to this type of phenomena. Am curious if anyone has experienced that? all insights are appreciated, thanks and happy meditation 🙏
