A tent is a temporary place to stay unlike a house, which is more permanent, so consider what's in your life right now that you don't consider a permanent fixture.
It could mean that where you're living right now is only for the present and you don't intend on staying there much longer. Perhaps you fear losing your home so you're trying not to get too attached to where you are living right now.
It can indicate that an idea in your waking life is not yet concrete or that you feel some instability or insecurity right now. If you give it time and your best effort, then you may feel more confident in its longevity.
Another interpretation is that it's a warning to you that the home you're living in at the moment, a situation or a relationship you're in has a rocky foundation and you may need to leave it behind.
Perhaps the dream is a result of feeling like you've taken a step back in life. You feel less secure than you did in your recent past because you've lost your job, your home or a significant relationship and it has left you exposed. Try to remember that you can rebuild what you had- just be mindful of what you’ve learned from the loss and how you can apply it to making a better future for yourself.
It's possible you need to travel more, and this is your subconscious telling you that it will be good for you and that you're secretly yearning to do so. Or on the flipside, if you love adventure- it might be time to settle down with your partner.
Another thought process is that you need a change in your routine- perhaps your body and mind is telling you that you need to take some time off, avoid the daily monotony and do something different.
