3. Semantic Satiation

There is nothing terrible or scary about this phenomenon. Sometimes you can notice that you have pronounces a phrase or word a few times and felt, after several seconds, that what you said lost its meaning. This sensation is called ‘semantic sensation’. If the word is repeated on and on, the brain gets too much of it and feels confused about the meaning.

4. Earworms

This unusual term was given to another weird phenomenon. Your brain works in strange ways and you cannot control its functions. You may sometimes have things stuck in your head for weeks. Scientists say that the problem is that your brain tends to get stuck in a mental look. For example, we can remember a certain piece of a catchy poem or song. Then we try to move on and remember the rest of the piece, but it seems impossible and your brain returns to the unfinished phrase. It keeps repeating on and on but all you can do is walk in circles. This sensation is exhausting and annoying and getting rid of it is not very easy.
