Have you ever had disorienting dreams/disoreintation causd by sleep pattern?

I just came home from school around 3:00 p.m. today and after awhile, I just completely knocked out on my couch, I don’t know why I was so tired. I have had irregular sleep patterns, like waking up every 2hrs. or going to bed at 3a.m. and waking up at 6a.m. but last night I slept well. Anyway I vaguley remember a dream about gangsters mixed with things that happened previously today. I wake up, and the clock says 6:15(it doesn’t say a.m. or p.m.) and the light outside is twilight-ish, similar to a sunrise. I didn’t know where the heck I was, then I get freaked out that I slept for 14hrs. but I realize that it is only 6:15 p.m. The effect of going through my day in my dream, mixed my screwed up sleeping patterns made me feel like I just experienced a whole ‘nother 24 hours. Also related, whenever I go to sleep for long periods during the day time, I feel like I missed a large portion of time when it’s only around 3 hrs. or so. Can anybody relate? If so share some of your thoughts on this as well as any experiences you’ve had. [:
