Are the following sentences acceptable?
1. In today’s society, each person might be under pressure in some ways, such as schoolwork, work, and family.
2. Some people’s slumber might be influenced because of being under too much pressure, so it will bring out insomnia.
You think Some people’s slumber might be influenced because of being under too much pressure is incorrect; I'm not sure whether it is because you think SLUMBER cannot be UNDER TOO MUCH PRESSURE. If so, I think the original sentence is OK, because when the subject can be traced, some grammarians will consider it acceptable, like Care must be taken when dealing with the problem, which is OK.

As I said, I underlined the parts which had a problem. We don't use "because of" after "influenced", we use a 2-letter preposition.
And we don't refer to insomnia as being "brought out". There is another phrasal verb which would work there which starts with "bring" and is followed by another 2-letter preposition.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
Sorry for the misunderstanding. I thought the sentence grammatical but whether it sounded natural to native speakers I didn't know.
For the other part of the sentence, the similar thing I can find in my favourite dictionary is:
bring something on:
to make something develop, usually something unpleasant
eg He was suffering from stress brought on by overwork.
