Hi Judy, i see that you are enthusiastic that you have experienced your dream forthe first time as a real time conscious real time event. You say that you took control of the dream but you are not in control!
since your dream is short, but with some confusion in the description of your dream experience, I will first introduce my standard model from which I interprete and explain most dreams just because you are new.
Standard:
The adult person, the ego who dreams, usually sees hisself in a house (his body) with his partner (husband / wife), who represents his / her Soul. Eventual children will then represent (an aspect of) his / her spirit.
Depending on the subject of the message that your Soul wants to convey through the dream, in combination with your current status (teen, divorced age ...etc), the standard figures 'take a different form / image. For instance, if the Soul wants to teach you something, the house may be turned in a classroom or a lecture hall and your husband represented by a former teacher. Or if it concerns a message about a disease, that spnace will be a hospital.
What is now also standard according to my experience of thousands of dreams is that being in a bus is synonymous of being member of a dark community, a diabolic cult (delibarately or without knowing / choosen for). Because in the normal situation when you are on your way (here on the bridge), 'on your life path', you should be in your own (private) car with your husband, your spiritual partner as a co-pilot (navigating, showing you the way) and you in charge of the steering wheel. Thus the car represent your body on the move, the mobile house. The body also represent the temple of God. Thus experiencing "being in a bus" is like saying that the "car", the mobile temple is not the sacred temple dedicated exclusively to God anymore, but the playground of one or more idols. And the result of this situation is that you are now "on a cliff, on the edge of a bridge", in a desparate dark situation, contemplating suicide pompted by a demon???
"I was on a bus. Which is on the cliff of a bridge" is not a positive Freudian slip of the tongue, because I think it's a combination of a cliff on the edge of the valley of death and on the edge of a high bridge: this indicates a desperate situation where you are bizzy to take your own life. Do not! The one who says to you " go back this is real and get out of this body " is your Higher Self, Your soul, God. It's a bit confusing what you / He says, what is said, but I understand. Pray call on Him and He will take you out of the dark world, that "bus."
