Hello!
Everyone can sleep, but it's complicated. Your description is brief, so I'll share my views. If they don't apply, ignore them.
[1] Reasons for trouble sleeping
The original temperament of the host is likely highly sensitive, sensitive to the environment, and alert.
The environment and changes in it can be seen as external stimuli. Some people are born with very sensitive nervous systems. Even the slightest thing can set them off. This makes them think they are not safe, so they can't sleep.
Light, sound, others, discomfort, unfinished matters, and uncertainty are all sources of stimulation. Some people may be sensitive to some of these, and the poster may be mainly sensitive to unfinished matters and uncertainty, but they should also be sensitive to sound. The poster mentioned that the family makes too much noise when they come home.
I don't know how old the poster is or if he's studying or working. Tasks have deadlines or schedules, and there are difficulties and obstacles. These are intense mental activities that can cause stress.
These activities and stress will activate your nervous system. If you stay in this state for a long time, it will be hard to fall asleep.
If the original poster is not highly sensitive, it doesn't affect the logic or conclusions. "High" is relative. Perhaps the poster's sensitivity is average, but academic or work pressure may be higher.
Sensitivity is just a way of describing how well a person adapts to their environment. If stress is greater than the nervous system can cope with, it can be described as "too stressful" or "too sensitive".
It could also be that the host has something important to do or is sensitive to something in a certain area, causing the nervous system to alarm. It could also be that long-term fatigue or low mood has caused sleep disorders.
[2] Possible ways to improve
Try anything that helps calm your nervous system.
Do the three or five most important academic or work tasks every day and leave the rest to chance. This means going to bed every night without any unfinished business, which reduces mental stress and allows your tense nerves to relax.
Similarly, you can let go of things you can't control by identifying the risks and dangers. This can help you worry less and reduce your stress.
After relieving stress, spend the time you have gained on improving your physical health. For example, prepare well-balanced meals, participate in recreational activities, chat with friends, or spend time alone doing things you like. Exercise daily. It boosts the immune system, improves physical function, and improves sleep.
Make your sleeping environment comfortable. Use soft or no light, earplugs to block out noise, talk to family about being quiet when you come home late at night, eat and drink before bed, and avoid mentally challenging things one or two hours before bed.
You can also try mindfulness breathing to relax. Slow, deep breathing and exercises can help relax your nervous system.
There are also professional methods like hypnotherapy, but you have to be persistent. Not every method is right for you, so you have to keep trying.
Perseverance is a luxury.
If the original poster is dealing with something significant, the above methods will be less effective. The original poster will need to deal with the knots first.
May you find the right way, sleep well, and have energy.
The above. Love you.

I can totally relate to that. Even with lullabies and soft tunes playing, my mind just refuses to switch off once I'm in bed. The moment I close my eyes, it's like my thoughts race through a million scenarios, most of which haven't even occurred yet. At least they're vivid, making me feel oddly awake. And don't get me started on being jolted awake by the loud thuds of latenight family activities; it ruins the rest of my night and leaves me groggy the next day.
It's frustrating when despite the soothing music, lying down triggers an avalanche of thoughts in my head. In the darkness, I find myself mentally running through hypothetical situations, at least they are colorful and keep me wide awake. Getting interrupted by family members moving around loudly late at night is the worst, and it always results in me feeling so sluggish the following day.
The quiet doesn't help either, as soon as I'm horizontal, my brain starts buzzing with thoughts about things that haven't happened. It's almost entertaining how lively my imagination gets, but not when I need sleep. Latenight disturbances from family members are no fun either, waking up from deep sleep due to noise really affects my mood the next day.
No matter the gentle music, my brain turns into a movie director as soon as I lie down, scripting scenes that are full of color and activity. But this mental film festival keeps me alert when I should be resting. Being awakened by sudden noises from family members who come home late is also a big issue, leading to days where I feel far from my best.
