The images are your creation. Your message, so the best thing to do is find out what they mean to you. If they are scary images then in all probably you are scared of something... possibly image streaming itself? Keep working with it, write down your image streams and what you think they are telling your. In particular look at the question you were image streaming for. Do you really want an answer to the question?
Notice also you are labling the images "negative and scary" yet you cannot describe their form... have you labled them before they have really formed? As for the face being scary... why not just describe it as different and describe it in detail? If you manage to let a 'flower' change form once you can let it change form again... the fact that you managed to for a bit 'see' a flower means you can bring the picture back or move on with your image stream.
When it happens start describing faster, keep going with it until the image stream finishes. Remember the images themselves cannot harm you, they only have a message for you.
