These are very interesting. I am not familiar with Marina's challenge but I suspect it concerns abuse. Before discussing the poetry, I thought the plural of Haiku was Haiku.
Angry roars, to me sounds like words hurled with force. I know words can be more painful than any physical slap. A slap may injure the body but a word can injure the spirit (soul). This strikes me as verbal abuse.
Under The Bed
A person bleeds in more ways than just blood. When a person, for who's approval you desperately strive, slaps you down, the pain cuts deep. The level of fear which drives a child under a bed is not a good thing. My second daughter, at age 4, dialed 911 and the police responded. She hid under the bed, afraid they would take her to jail. I found that I had a fair amount of spiritual rebuilding to do before begining to instruct.
This could be interpreted both ways, as physical and/or mental abuse.
This strikes me as the downpour of tears from crushing frustration...drowning in its murky depths. The dispare is made all the more poignant by the final plea. Excellant writing!
Overall, I find these three haiku focused and well written. The secret to Haiku is to limit your subject and distill what you want to say down to the essence. Having only 17 syllables to work with, words can not be wasted. You have certainly been successful here. You should be justifiably proud of your work. I look forward to reading your work in the future.
p.s. This type of "more in depth" analysis is usually reserved for the "Critical Analysis" Forum. However, since you asked, I am happy to critique your work here.
