Asking for signs is not always easy we can become scared or we can have
different expectations of it and how to do it. Do we ask it out loud or do we ask it inside our head?
Well both are good of course it depends on what suits you the best and what way you think works the more effective but there are other options to ask for guidance.

Writing: Write down what you ask for even if it is on a memo for the universe it doesn't matter that much the order is clear.

Meditation: Well it is technically asking inside your head but you can manifest or visualize the feeling you want with it. Asking for guidance and the right positive feelings can help to put the
question on a higher energy vibration.

Lighting a candle: Candles are another perfect way to communicate wit the universe simply light the candle and ask out loud what you want, this question has an own vibration and the candle can put it straight to the cosmos just like the mail man.

Angels: Your guardian angels are here for you to help you don't make them bored ;)

Daydreaming: Daydreaming is in my opinion mediation but then with the eyes open it makes you calm you think and visualize what you want, it is true that you don't have control over it but the point with daydreaming is you think about what you desire wich is actually the same as thinking but daydreaming is more in a peaceful way.
