Your dreams sound intense and certainly carry a lot of emotional weight. The themes of violence and control in your dreams could reflect various aspects of your waking life.

1. Violence and Fear: The violent imagery, like the clown figure and the bomb, might symbolize feelings of being threatened or out of control in some area of your life. Clowns can often represent fear or anxiety, as they are traditionally seen as both entertaining and unsettling. This juxtaposition might indicate a conflict you're experiencing in your daily life, perhaps related to a situation or relationship that feels threatening.
2. Controllability: The fact that you can control your dreams and wake yourself up suggests a strong self-awareness and perhaps a desire to escape from the distress these dreams cause. This ability could indicate that you have the tools to confront whatever is causing you anxiety, even if it's manifesting in such extreme ways during your sleep.
3. Disturbing Experiences: The sensation of feeling like you are being pulled out of reality, along with the mechanical noises, could suggest feelings of disconnect or overwhelm. It might be worth considering whether you're experiencing stress or pressure in your life that might be causing these heightened sensations.
4. Recurring Themes: If these types of dreams are recurring, it might be helpful to reflect on what might be triggering them. Keeping a dream journal could help you identify patterns or connections to your waking life.
5. Emotional Health: If these dreams continue to disturb you, it may be beneficial to explore them further, possibly with a therapist or counselor who specializes in dream work or anxiety. They can help you unpack these feelings in a safe environment.

Overall, dreaming can often be a reflection of our subconscious mind processing experiences, fears, and emotions. It might be worthwhile to explore what in your life could be contributing to such vivid and intense dreams.
