Have you ever? and some question

Have you guys ever create/spawn a cartoon/anime character, or even the environmental and interact with it, im curious to know what would happen, would be like the same as 3D human being/objects.

Questions.
Is it possible to look at a face clearly, or it becomes a blur, like not just knowing the person is there and just scan there face really quick, but really focusing on their face and clarity?

Why do fights never "satisfy"" me. I've had 4x where i punch my cousin (idk why lol) and for some reason he doesn't seem to get hurt or show any emotion, and i feel that my punch are always ineffective...

I've heard people lucid for 10 minute +, and to me it's just shocking. How can you make it that long, you must be doing some boring stuff to maintain it -.-.
Anyone did 30 minute +?, not the feeling of 30minute, but 30minute in real time (estimate), in the dream.

I would guess for the anime/cartoon, they'd look 2D, but you can go around them and you can see the rest of their animated bodies.

It's possible, you just gotta improve the vividness/clarity of the dream.

I don't know why they satisfy you, but try expecting an epic fight when you punch a DC.

Keep Dreaming and your time spans might increase, but IDK really. I don't know about 30 min. of real time, but I know a few hours of dreaming in a 10 min. nap or REM sleep.

When I summon Anime/manga characters, I see them 3d, they look surprisingly good lol
Yes, it is possible to look at faces and see them clearly.
You need to practice more in your fighting skills, then, or explore to find stronger DCs to fight.
I have had 30+mins lucids, solely based on fights. I'm an huge fight addict, so a lot of my lcuids involve them. I remember the fight with Nerimeno (Only the fight) lasted somewhere around 20 mins.

Looking at a face: Yes, I've seen faces very clearly- both of famous people, people in my real life, and dream characters that only existed in the dream. Usually my dreams are either very detailed and vivid or action-packed- never both. For example, if I dream something in which I can see everything clearly (faces, clothing, furniture, trees, etc) then usually the dream is really slow and mellow and not much happens (just sitting around talking, often). But if I dream something full of action (a chase, an adventure) then I can't see people clearly.

I only managed to stay lucid for a full dream one time. The entire dream took just a few minutes (though it could've been longer perhaps if my alarm clock hadn't gone off) but it felt like I spent an hour there. I had the feeling that a lot of time had passed. How would you know if you had a lucid dream for longer or shorter than that unless you are in a situation where you see the time before and, then wake up and see the time? Just curious.

I have had dreams with cartoon characters in them (not Lucid, sadly... well, the only lucid with a cartoon was a small cat that was there for a few seconds). They looked like completely 3D existing 'people' that fit into the world fine. Completely believable, and they still looked like their real-life counterparts. I think once you sorta know what a cartoon looks like, your brain can fill in what they would look like from all angles, making the character easy to portray in a dream.

As for the length of the dream, it is a matter of keeping your excitement in check. (Also you want to make sure you are lucid near the beginning of the cycle, rather than near the end so the dream doesn't get cut short) If you can keep your excitement under control, you can keep dreaming with ease (generally speaking). If you come to the end of your dream too soon, just chain it into another one to continue it after you wake up.

Would the interaction with water wake you up? Like if you were to jump in a river in your lucid dream, would it wake you up? (no not an inception movie question).
I remember in an average dream i was in some water environment and i could breath underwater but don't remember if i woke up from it though.

I wanna know because i want to add some water element when i have the chance for my next lucid dream

Nah, it won't wake you up, diving and swimming are common in lucids.
