Berry- how did you know what guides they were?
I see the flashes all the time, dozens every day. As some say we are just starting to go into higher dimensions, new energies on & around us... very generic explanations. Doesn't help that it's your spirit guide if you don't know what they are saying, right? I do hear my spirit guides- or surmise what's what thru constant discernment, if the sparkles (my flashes are tiny sparkles) are them, that's nice, but I wouldn't know how to confirm it.
