Sunburn psychological effects ?

I never go too much in the sun as I don't like Sunburn. Recently I had a very deep hallucination with a Sunburn, almost similar to weed smoking without the bad side effects.  I wonder if it is due to the Sun or it's a coincidence. Anyone noticed any psychological effects while baking in the Sun? I live in a tropical area so the Sun here is quite strong. I still don't know if it's a spiritual experience or it all happened in my mind. I'm not the kind to be emotional or cry or anything but I did a lot of meditation recently, about 3 hour a day.
