3 Weird Questions about the Human Body and Mind: Do You Know the Answers?
Question 1: Why do I often experience deja vu?
We all know what deja vu is: an obscure feeling that makes us believe that an event we are experiencing now has already happened in the past.
This phenomenon occurs more often in people who suffer from migraines (especially if the pain is localized in temples), which often cause nerve excitability in parts of the brain that control memory. The result is the sense of having previously experienced an event or a situation that is occurring at the moment.
Question 2: Why do I have a falling sensation just before falling asleep?
Experts call it “hypnagogic jerk” and some scientists believe that it is the way our body tries to keep us awake. For example, if you are extremely sleepy and someone is speaking to you, then you can feel the hypnagogic jerk.
But it also happens when you fall into your bed to get some sleep: while you have already fallen asleep, some external noises cause stimuli in the brain and as a result, you feel like you are falling down and wake up immediately.
Question 3: Why can’t I tickle myself?
When someone tickles us, we startle and start laughing and shuddering. This happens because of the stimulation of nerve endings in the skin, while the feeling of tingling is generated in the central nervous system.
If we tickle ourselves, it will not work as the most important element is missing – the startle.
