What does it mean when your dreams feel so real?

It could mean that it's a suppressed memory from the post. A dream that closely resembled a true event. Perhaps, something that you might have seen or heard unconsciously as well.

Some people have different opinions on this, but I just think it means that you are very deep in sleep. I don't really think it has anything to do with it being more real or fake, but that's just my opinion!

Most of the time what we dream is totally imaginative and nothing happens in real, one should not focus on what has happened in dream

Absolutely nothing at all. Dreams are just dreams, when you open your eyes it is not a part of your reality. Always value the reality that you can actually know and experience in your awaken and conscious state. Nothing else is ever real.

Sometimes your dreams could mean something that is happening in real life, E.G if you are falling maybe you fell out of bed.

It means that you have a strong memory! That you are actually able to recall every single detail, no matter how short the dream was.

The dream could have been a memory. Sometimes also the dreams feel so real because your subconscious can be a powerful thing. I wouldn't think so deep into it though. Your dreams cannot hurt you.

I think that everyone have this sometimes, you can feel very happy or sad after you wake up. The best thing is just to forget it and not to bother you.

My dreams always feel so real that I wake up crying or feeling insecure but dreams are dreams. Not reality.

It just means you were in a deep sleep, happens to everyone. It could also be portraying an underlying issue in your life. Let's say your dream involved you losing a tooth. google 'what does it mean when I dream of losing a tooth?' Some dreams reflect your emotions and day to day thoughts. Some dreams are just there. Last night I dreamed of mushrooms chasing me. I love mushrooms. There's no significance there. Sometimes you just have to move on. Goodluck!
