Brown, yellow and red light during meditation

[Lion Roman]

Hello everyone, this is my first post in this community.

First I'd like to thank you all.

Yesterday, While meditating in my backyard, After a long while my vision field within my closed eyes became filled with a red circular color which expanded and eventually encompassed my entire vision. Shortly after brown and yellow proceeded.

I have experienced things like this in the past, I was maintaining a lotus position during this time, It was strange, yet comfortable, has anyone any insight on this occurrence?
