Middle of high summer and digging through stony clay.&lt;p&gt;Interspersed between the digging were numerous patrols and mental tests.&lt;p&gt;I experienced the hallucinations whilst fully awake from about hour 76 particularly throughout the night and early morning. I vividly remember stopping so talk to a Colour Sergeant I knew and shook his hand, only to find it extremely prickly. Trying again the pain brought me to my senses and I realised I was shaking hands with a Holy bush.&lt;p&gt;During a dawn attack the following morning I frequently fell into micro-sleeps whilst &amp;#x27;standing to&amp;#x27;, resulting in bashed knees and a couple of trips to the bottom of the trench flat on my face.&lt;p&gt;Come an enforced rest period at hour 86 I lay down and experienced the kind of unconsciousness I&amp;#x27;ve only experienced under an anaesthetic. I was utterly gone.&lt;p&gt;3 hours later I felt amazingly refreshed, just as well as there were 48 more hours to go without sleep until the exercise finished.</text><parent_chain><item><author>otherusername2</author><text>I once, involuntary, went without sleep for around 72 hours.

When I mess up my sleeping schedule pretty bad (which happened a lot back in college), I usually do sleep paralysis when falling asleep (as opposed to when waking up). And I can do it 6 or 7 times in a row, it&amp;#x27;s a nightmare. Usually though, I realize what&amp;#x27;s going on (it&amp;#x27;s happened to me so. many. times.) after the second or third &amp;#x27;paralysis&amp;#x27; and sleep on my stomach, which for some reason, allows me to fall asleep without the whole paralysis thing going on. You can actually turn sleep paralysis into a lucid dream if you &amp;#x27;control&amp;#x27; it properly. I usually just wake up thinking &amp;#x27;thank god I&amp;#x27;m alive&amp;#x27; though.&lt;p&gt;For those interested in sleep paralysis, wikipedia&amp;#x27;s got a pretty good page about it:
&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Sleep_paralysis&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;en.wikipedia.org&amp;#x2F;wiki&amp;#x2F;Sleep_paralysis&lt;/a&gt;&lt;p&gt;Sleep is truely fascinating.</text><parent_chain><item><author>otherusername2</author><text>I once, involuntary, went without sleep for around 72 hours.
