Hello
If I may I would like to try and interpret your dream if so here it is...The airplane and car in your dream represent the anxiety and the out of control feeling that you have in your waking day. I don't think your bf is cheating on you it just feels like that because of the insecurity that you are also feeling while awake. (some guidance)You are in control of your mind, don't let your mind control you. Tell the images that you see in you mind, are not real and you cannot hurt me. Meditation is good and being kind to yourself treat yourself to something nice once and while I did. Also avoid caffeine at bedtime. Herbal teas are great and you can buy ones now that help calm you before bed. I wish you all the best
