One friend of mine told me when she was living in Japan, she liked to end her sentences with ん (maybe instead of の).
Examples:
明日学校にいくん？
明日学校に行かないと思う…風邪引いたん。
Actually I've never seen it! But my friend told me they used it!
I just want to know if it's possible. And if Japanese would think it a little strange if I said ん instead of の.
Your two examples are incorrect in the “standard” dialect.
Some dialects (such as the Gunma dialect and the Saitama dialect) use ん instead of の in a question as in your first example. The second example may also be used in some dialects.
ん and の (deletion of the vowel).
if you wanted to end with just ん without the です you should probably just use the informal of んです which is の
明日学校にいくの？
明日学校に行かないと思う、、、風邪引いたの。
ん like tsuyoshi said, is a dialect version of の seen in various regions of Japan. While it doesn't seem to be used in Aichi, all of my co-workers know of it. So it could be said that you can use it and you will be understood, but it is definately not standard japanese.
I can't think of one time I have heard that...Not to say it hasn't happened. Using the whole んです smoothly was stressed at school, as it makes your Japanese sound really natural. So I think I would notice if I heard someone end on the ん...I would stick to the normal usage until you hear a native speaker use it the way your friend did.
