Is this Hypnagogic Imagery?

[Kanious]

Hi people...I'm a wilder...But when i wild [i wild when i'm too tired, and enter in SP in seconds, and in a LD in like 3 minutes, so i never put attention on HI, and i don't know if i had it someday] in normal days, like yesterday, i was trying to wild... I haven't feel the SP...But there was an time that i saw my home, but so dark...Like i could see with my eyelids closed... I don't know if this is Hypnagogic Imagery...Can someone help me? Here are an image that's like i was seeing with closed eyes [great purples balls with images inside running at my eyelids, sometimes i was focusing on it thinking about it]: I'm here waiting for some tips to induce this to SP...
