Interesting and slightly more than coincidences. B where did you post your darkroom experience I do not recall reading it.
It seems your experience is showing you that you are not awakening your pineal gland rather it is already activated and you just need realize this. The best way is to just trust these experiences and forget about it consciously simply allowing the pineal to function on the most appropriate level which is not necessarily consciously the benefits can then exceed what is expected and the experiences will not cause suffering as can happen with desire and such.
