1-- An explanation difficult to believe; an unlikely tale.
2-- if it's an idiom, I don't know it; 'tonnel' should be 'tunnel'; 'on all fours' means crawling on one's hands and knees.
3-- 'Like' is not needed; we are very similar. The full proverb is 'birds of a feather flock together': people of like mind are found in the same places or doing the same things.
4-- 'Horse', not 'house'. A 'dark horse' is an unexpected winner or an unheralded contestant/candidate who is considered to have a good chance of winning.
5-- to go through many difficult, or all kinds of, experiences.
6-- Never heard it. Here is what googling got me: "Below the Salt - This, at its most vivid, can be found in the use of salt at the medieval food table. Here salt [an expensive and rare commodity of the time] was placed at the center of the table. Above the salt sat the family and intimates of the household, below the salt sat the servants and dependants".
7-- You hear it (usually a rumour).
8-- Is that the correct way of saying/expressing that?
