I just had this dream this morning, where I kept seeing a black & orange spider, it would follow me at times or keep out of my way but on items in my room. it would always be purring like cat purring but loud, in dream I also kept trying to hit it and kept missing, I don't like spiders near me at all. also I did manage to kill the spider but it kept purring until it's head was squished. that was when I woke up after finishing it off. 
I do feel bad for killing the spider in my dream even in real life.
I will admit I have been feeling worried and stressed about something personal so I wonder if it has anything to do with that.
I am just confused if it's same meaning as spider dream or a bit different, like if there is more meaning. it never made web or was hanging from web.

what do you all think?
