Explain what you visualized and what you imagined from the sense imagery language, while reading this stanza of the poem.

Well I visualized that I had something on the floor and then something started rustling and then someone called my name. And then whatever was on the floor turned into a girl and said my name and ran.

Explanation: This sounds a little weird right now but I promise you I AM NOT MENTAL it's just what I would of wrote down for my answer. -_-

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.
