This is probably one of the hardest considerations when writing fiction. I have been told I should stick to past tense because I have more flexibility with going deeper into character analysis and speaking the mind. I have read stories in both past and present and I do not find much of a difference. Never the less, Tense shifting. I was told that when it is happening in the present or 'real time', stick to present tense. When it happened in the past, write as if it had already happened. However, when writing in present tense, when a topic happened in the past, what are the rules with shifting the tense from present to past. An example I came across with my writing was, in the beginning of the story I described a dream the MC had the previous night. Then it jumped to present tense with what was happening now. As the character narrates the actions happening in the present, there are moments when the MC reflects on the past and uses past tense. Would it be easier to just make the entire story past tense or it this a rule that is acceptable. Ex: (writing this as an example). Last night was one of the most frustrating nights I have had in awhile. Everything did not feel right. The bedsheets were too stiff, the blankets were bunched up and the air conditioner seized. Tossing and turning, I could not find the comfort I would have to drift me to sleep. I wake up this morning with only three hours of restless sleep. Unfolded clean clothes are scattered on the foot of the mattress. I was in a rush and must have forgotten to fold them and place them back into their proper place.
