Reviews for each:

1st one- This one had an interesting idea behind it. I liked it.

2nd- "Dream up your warmth", another interesting thought

3rd- This one is pretty good.

4th- I liked the last one better, but it's not bad.

5th- It's okay...

6th- The "dreamed" and "dream" feels a little repetitive.

Okay, overall I see one main problem... these are not technically haiku (no s when plural). Haiku are three lines (you got that part down) but there are 5, 7, the 5 syllables. You've got something like 3, 5, 3, or thereabouts which isn't the usual haiku form... However, you do seem to have a grasp on how they're supposed to sound, so 10 brownie points for that :) Keep up the writing and have a nice day!

Also, feel free to check out some of the haiku I've written ;)
