Last night for instance.
Where I had, repeatedly, what was either both audio and visual hallucinations while half-awake and half-asleep, or literally the most lucid dreams of all time where I was picture-perfectly recreating every single detail of my house at night save for the imagined details of family members walking about who weren't actually walking about.
One of them was hearing my mom get out of her bed (her bedroom is in the hallway and each bedroom has a distinctive sound to the door opening), going to the bathroom, yelling at an animal presumably our dog, and then going back to bed. Included in this was turning on the bathroom light, a sound I could hear.
...My mom is in Oregon right now. I legit had the thought, "maybe she arrived home overnight?" because it was that real to me.
And another involved my sister interacting out in the living room where I'm sleeping during the time my parents are away. I "woke up", saw her, tossed and turned, tried to ignore the noise, sounds, light, and so on and so forth she was generating with her presence and tried my hardest to go to sleep.
Sounds plausible enough as having been something which really happened, right?
...Except it didn't. My sister was in her bed at the time, fast asleep. So whatever that was I saw, it wasn't real.
You can imagine what effect this had on my sleep.
Because I was being woken up by nonexistent disturbances, which my thought was more or less "I need to ignore these disturbances and go back to sleep".
I didn't sleep well last night.
If similar happens again, tonight will be hell.
Still, gotta try.
