Back to Biphasic - Day 2

Last night I decided to give myself a sleep in. To do that I ended up falling asleep at 11:00pm for my nap, and falling asleep at 4:15am for my core sleep. It took me about 20 minutes to fall asleep on my core as only 3.75 hours had passed since I had taken my nap and I was still quite awake. I had to take my core earlier because unfortunately my mum won't let me sleep past 9:00am. It wasn't a major problem though, I just did a low key activity all morning, namely watching Supernatural, so that my mind didn't end up so stimulated that I couldn't fall asleep at all.

Here's the chart for my first nap:



As can be seen, it was pretty restless, and in actual fact I remember waking half way through. Once thing that is interesting is that half way through I seem to be having dreams from a period of anywhere from 5 to 10 minutes, and then again at the end for 5 minutes. I can never remember full dreams however, I only ever have fleeting images upon waking. As soon as I try to put words to these images, they get lost and I can no longer recall what they were. I don't actually know why this happens.

My core sleep was about 4.5 hours altogether, giving me a total of 6 hours sleep. I have to say it felt like an eternity seeing as I haven't slept more than 5.5 hours in over a month. I just want to say how bad my back ached when I woke up. Everything felt severly stiff, and I was feeling sleepy all morning, although not tired. Here's the graph:



Key:
4 = Awake
3 = REM (dreaming)
2 = Stage 2 Sleep (Light sleep)
1 = Deep sleep

There was virtually no deep sleep in here, although it seemed to be interspered in small 5 to 10 minute increments, which is too fine to graph here. In fact overall I barely had any deep sleep, I don't know why that is. Note though how similar it is to yesterdays core sleep chart, bearing in mind that today I slept half an hour longer:



I am starting to see a pattern here. Based on this information, I'm going to put my alarm on for 3.5 hours tonight, giving me a period of 15 minutes to fall asleep and my smart alarm a period of 15 minutes to wake me up. I seem to be having about half an hour of deep sleep and an hour of REM, but I'm slightly concerned about all that stage 2 sleep in the middle. It makes up for nearly an hour. I suppose it is important though. It'll be interesting to see what my graphs will look like after a week.
