Mind-boggling optical illusion reveals your biggest fears... but what do YOU see first?

Whether it's something as simple as creepy crawlies, or a much darker fear, most people are reluctant to reveal what keeps them awake at night.

However, a mind-boggling optical illusion and personality test claims to identify your greatest fear, simply based on what you see first in an image.

The test, which was shared by Times Now, has also been widely circulated on social media, with users dubbing it as 'so accurate'.

At first glance, the illusion is just a black and white drawing, but there are two potential things you could see first in the image.

To take on the brainteaser, glance at the drawing below and note what you see first - then scroll down to see what it means.

A rodent

If you saw a rodent first, which is in black on the top half of the image, it means you have a fear of relying on others.

You love being independent so ridicule and humiliation would be your worst nightmare.

Noticing the rodent first means you strive to be self-reliant and you're terrified of facing pity or mockery, as they would hugely knock your confidence. 

You need to have full control over your life and don't like to allow any outside influences to affect what you choose to do.

It also means you're a responsible person and one of the things you hate most is asking others for help.

A man's side profile 

If you missed the rodent, you would have seen the man's side profile first, with the creature making up his hair.

Seeing the side profile first means you have a profound fear of isolation and solitude.

Unlike people who saw the animal first, being around others is essential for you as you need that human interaction.

You are capable of being independent, however, your support system is very important to you so you're terrified of it being pulled away. 

Having someone you can rely on is of the highest importance so being completely alone is your deepest worry.  

The mind-warping test was also shared by @psychologylove100 on TikTok, with commenters writing: 'Sir, why are you always so accurate?' and 'That's me! I always tell my daughters to let me do everything by myself, it's not because I don't like help but that means I'm healthy and happy.'

Others added: 'I see a side view of human head, I'm not afraid of being alone, being alone means peace of mind' and 'Why do I see both at once?'

If you enjoyed this personality test, there are plenty more brain teasers and illusions to try. 

Another optical illusion can allegedly reveal a person's true personality depending on what animal they spot first.

The black and white picture, shared by Times Now, depicts both a cat and a mouse.

The test can reveal whether a person is independent and curious or has a more cautious personality.

Simply glance at the below image and see which animal catches your eye first, then read on to find out what it means.

The black and white picture, shared by Times Now , depicts two animals - which one you see first will determine your biggest traits

If your eyes naturally wandered to the black cat, which is the largest part of the image, it means your personality traits are similar to those of the feline animal.

You are independent and curious, while also being mysterious and playful.

Similar to most pet cats, you don't rely on others and prefer to do things yourself.

You're curious by nature and always looking to learn new things and ask more questions.

You can easily switch between work and play and you often lure others in with your mysterious personality.

If you saw the mouse first, which is smaller on the page, it means you are more cautious.

You may be quite shy and reserved, however this doesn't mean you aren't aware of your surroundings.

Those who saw the mouse first are observant as well as timid - they are always watching what's going on around them.

You are also adaptable and resourceful, knowing what to do when faced with problems and difficult situations.
