This is my first time posting and I need help. ’The sunlight shone dimly through the curtain.’ Does it make sense? Is it suppose to be shined instead of shone? I feel something is wrong but I don’t really know.
The two forms of past tense/past participle of shine are both valid: shone and shined. Shone usually appears in the verb's intransitive usages, while shined tends to be transitive, not without exceptions of course. "One shined their shoes." and "The light shone brightly."
The verb conjugation is perfectly fine in your sentence, but I am not fond of the subject and the complement. I would say:
The sun shone dimly through the curtains.
The Oxford Dictionaries Online has a nice passage about this:
The verb shine has two past and past participle forms, shone and shined. The form shone is generally preferred when the verb is used without an object, as in the sun shone brightly. When shine is used transitively, the form shined is usual when the meaning is ‘to polish’, but both forms are used when the meaning is ‘to direct (a light)’. Conventions regarding usage of shined and shone are generally less rigid in US English than in British English, and it is not unusual to see either form used irrespective of meaning even in carefully edited texts
