@Saurna, It is. Dreams don't carry out into the real world. Your arm would not swell. I'm gonna assume you're very young. Partly because of the grammar. Mostly because of the silly lies.
@Bengolong, I can't convince you my nightmares are real. You're free to believe as you choose. But fun fact, things that happen in dreams are a reflection of things that have happened or are happening in real life—Never dreamt you were stifling only to wake up to the cat on your face? The swelling was due to mosquito bites, my arm was out from under the covers. As well the language was deliberately written that way. I used that nightmare to tell a story which is part of my "Stories from Grand-Mother" collection, the 'Loogaroo' chapter. I simply lifted it and made minor additions, namely the first sentence and last paragraph. Thanks for believing I'm young though, you've just made my day!
