soooo I'm guessing this was an insignificant experience where all that was happening was an entity was trying to make itself look a hell of a lot more important/powerful or whatever
In general that is not a modus operandi that one usually encounters. There is no benefit to this kind of action, for the spirit.
To better understand, tell us what events transpired afterwards. It may be something you didn't think about, but consider any events in which you had any vaguely similar sensations. The same emotional feel, you could say. And by events, I don't mean supernatural events, I mean even everyday things - grades in school, missing keys, mispelling words in just such a way. I would assume that you probably didn't keep a close journal of every event of every day, but that would be helpful!
This kind of appearance usually is attached to other events. Entities don't really care to impress you, startle you, etc., unless under duress from you and in those cases you have to have leverage on them of some sort to warrant the effort. The length of time seems very significant as well - it's about the length of time it would normally take for one's mind to process and event into dream-time. It's rarely the same night unless our mind is entirely occupied by a subject. Usually a few days to a few weeks later a sufficiently strange even pops up in dreams. I'm not necessarily saying you certainly dreamed this event. But, you say that you didn't process how strange it was until the next day. That sort of implies that your dreams might have confused your waking experience that night. This happens with a surprising amount of regularity, especially for people who are light sleepers. For instance people susceptible to being awoken by the need to use the bathroom.
So, as vivid a memory as it may be, give some consideration to the actual story itself, from your own point of view - would you really have not been affected deeply by seeing this on your way back to bed from the bathroom, out of no where? Were there follow up events that indicated the influence of any kind of spirit, much less the particular spirits you tried to summon? Have you had other experiences/dreams/etc., of this particular entity?
