but actually there are some scientific explanations to it as well as superstitions about this "witching" hours.

True! What made me almost believe it is that at this particular hourz strange noises that are not always heard in the day are heard and most of these witches brew their portions by these time because we mere mortals must have been fast asleep.

For me tho, this is the time I have peace and also a clear mind as you stated to read. If I read during the day when the sun is up and vehicles are moving around, I tend not to understand quickly as it'd be by 3am.
