A Quiet Meditation

I tried a longer meditation this morning - 30 minutes this time rather than my more usual 10 to 15 minutes - a few odd things happened; at one point a square flash of light occurred, later I could feel my daughter's hair against my cheek...it was as if she was leaning against me.  In other meditations, I'm a bit disturbed by all the sounds that I can hear; the ticking of the clock, our dogs or cat, birdsong outside; but this time I don't recall hearing anything at all.  All the time I was able to bring my thoughts under control and centred on my breathing, counting mainly on the out breath.
