Some days I can sleep all day and all night, only being awake for a few hours during the day, others my sleep is normal and others I will be up all day and all night with no sleep. I have really vivid dreams, normally crazy and wild when I sleep for 10-13 hours at night and as of now, when I've really noticed this happening, I'm not working. Although when I was working sometimes I would have to be up and out of the house by 9am and I wouldn't go to sleep till 3-4 in the morning. I just recently had all sorts of tests done for another issue I"m having & everything came back okay but I'm just curious if there is a name for this occurrence and trying to find this online only leads me to babies or insomnia. I plan on speaking to my doctor on my next visit but was looking to get some insight. Also, I'm a 22 year old female if that matters. Thank you in advance.
