>>838 there are various reasons you might feel this way that I can only guess.
I think the key point to remember is that such ‚µ‚¢ adjectives are generally used to express the speaker's own feelings and impressions.
So in that vein, it sounds kinda freaky to hear "I'm nostalgic" "this is nostalgic" (since we tend to use the very concept as an indictment of others) over "I miss" "I yearn" "those were the good old days" etc.
At the very least, one is more likely to say one has nostalgia. Verb-object, instead of adjective, thus using more active-voice subject-verb, as natural English is more prone to do.
