You can - but you probably don't want to. When you say "I'm feeling protected" it means that you feel like someone or something is protecting you (or you have the same feeling as when someone or something is protecting you). You are not the one doing the protecting - you are the object of the protection. If you said "I'm feeling enjoyed" it would mean that you feel like someone or something is enjoying you. You are not doing the enjoying, you are the object of someone else's enjoyment. Most of the time, that's a weird thing to say. You probably want to say "I feel a sense of enjoyment." or "I have a feeling of enjoyment."

You can say “I’m feeling a sense of enjoyment” although it’s not a very common sentence. #1 also works as long as you add the “a” (I’m feeling a sense of security.” “I’m feeling enjoyed” doesn’t work though because enjoy can’t be used as an adjective, unlike “protected” which can be both a verb and an adjective. I hope that helps!

Feeling grateful to you Alfredo lol

Thank you Suzy ! That’s very clear and wonderful thanks

Don't forget the "a" in the first 2 sentences. you can say : 1. I'm feeling a sense of security 2 I'm feeling a sense of enjoyment or 3. I'm feeling enjoyment it sounds better to say "I feel enjoyed" "I feel protected" "I feel secure"
