Something strange happened yesterday night. It is about a chain of images that I saw while sleeping, in dreams.

The following are the sequences I saw:

At 1 am, F 4 6 T

At 2 am, E 4 1 N

At 3 am, I 5 0 I

At 4 am, R 4 9 U

At 5 am , H 3 5 F

At 6 am, I did not see any images or dreams.

At 6: 30 am my friend came and knocked the door. I woke up. The end!

I strongly believe that these images/sequences were following some pattern.

I am wondering whether I would have seen anything if I was asleep during 7 am? If yes, what would have been it?!

Help me answer these mysteries please.

  • $\begingroup$ If you don't have clocks how do you know what time you saw the images? $\endgroup$

  • $\begingroup$ @Bazul But it only makes sense if you know the dreams occurred on a particular hour and not before or after - so there must be a source of time. It's also very peculiar to say "I have my mobile, but no clocks" - there literally isn't a clock in any bedroom in my house - we all use our mobiles for knowing the time during the night. $\endgroup$

At 7am you would have seen:


Take the hour to be N
the first column letter is the Nth letter in the word Nth
e.g.: The second (first column) letter, E, is the second letter in the word 'second'
The last column letter is the Nth from the end of the same word, ("Nth last")
e.g.: The second (last column) letter, N, is the second last letter in the word 'second'

If you assign a numerical value to each letter in sequence (A = 1, B = 2) you can sum the remaining letters of each word to product the number in the middle.

SeCOnD = S+C+O+D = 19+3+15+4 = 41
Combine these to get E41N

Following this pattern for 7am:
The seventh letter of 'seventh' is H
The seventh-last letter of 'seventh' is S
Summing the remaining letters, sEVENTh: 5+22+5+14+20 = 66

Combine them to get H66S

Nothing happens on the sixth hour because:

The word sixth has no sixth letter, so it can't be used, giving you a single hour of dreamless bliss.


Well, a partial answer goes like this:

The first letters of the sequence represent the 'letters at respective position of the hour spelt'. That is First, sEcond, thIrd, and so on.. and the last letters are the letters in the reverse sequence. That is T is the first letter in reverse of FIRST, N is the 2nd letter in reverse of SECOND, and so on.

Hence, a fraction of full answer is

H _ _ S ( for seventH hour, that is 7 AM)
