Only thing i can visualize is my gf’s eye

i have never been able to visualize anything at all whatsoever. on the apple test i see absolutely nothing. however ive noticed recently then when i go to bed and close my eyes, if i really think HARD i can distinctly make out my gf’s eyes in full colour and everything. it takes a little while but its the first time ive wver done it and im HYPED. anyone have any idea why that is?
